Tshawb xyuas qhov kev sim ua tiav ntawm cov qauv ntawm Hudson lub cev rau kev foob thiab kev tiv thaiv.
* Tus kws sau ntawv: Qee cov duab hauv zaj dab neeg no tuaj yeem cuam tshuam rau cov neeg saib.
Hauv nws cov lus qhib, tus kws lij choj Vince Biskupic tau hais tias cov ntshav pom ntawm Ken Hudson lub cev tuaj ntawm Shanna Van Dyn Hoven, tus tub ntxhais kawm kis las ntawm University of Wisconsin-Madison lub tsev rau lub caij ntuj sov so uas raug tua tuag thaum khiav ze nws lub tsev hauv Kaukauna.
Cov tub ceev xwm cov duab qhia pom Hudson sab laug txhais ceg liab, ntab liab ploog, zoo li nws pw ntawm tes rau hauv tsev kho mob lub txaj. Cov yam ntxwv khiav ntawm nruab nrab ntawm nws lub duav mus rau nws txoj kev khau khiab, me ntsis kev sib cav ntawm nws tus ntiv taw. Nws yog ob peb teev tom qab tub ceev xwm ntes Hudson tom qab lub tsheb li 16 mais ntawm Wisconsin Wisconsin Fox Valley lub Rau Hli 2000.
Hudson raug ntes tau tuaj tom qab Dave Carnot, tus kws txuas hlau, tau hais hauv kev xam phaj rau zaj dab neeg no tias nws tau hnov nws tus neeg zej zog, Van Dyn Hoven, 19, qw txog peb zaug. Tus tub ceev xwm, tus tub ceev xwm ntawm Kaukauna tus tub, tus tub ceev xwm hais tias nws khiav mus rau Plank Road qhov chaw uas nws pom Hudson sawv ntawm nws lub cev. Ib pliag tom qab ntawd, Carnot hais tias, Hudson dhia zoo nyob hauv nws lub tsheb thauj khoom thiab sim ua kom nws khiav ua ntej yuav khiav.
Biskupic raug liam Hudson tau tawm tsam Van Dyn Hoven nyob rau hauv qhov tsis sib haum ntawm kev npau taws tom qab Hudson, nws niam thiab nws tus hluas nkauj tau sib cav thaum lub sijhawm mus ncig ua si pw hav zoov.
Tab sis rau 17 xyoo, Hudson tau sawv ntawm nws qhov kev thov ntawm qhov tsis muaj txim - tias nws tsis tau chwv Van Dyn Hoven, uas nws tau hais tias nws pom muaj qhov raug mob hnyav heev. Tus kws tu lub tsev nrog cov ntaub ntawv txhaum cai, Hudson tau liam tias thaum nws pw tom qab ntawm ob pawg tub rog caij tsheb, cov tub ceev xwm tau nchuav thiab smeared lub tshuaj liab liab rau nws.
Cov txiaj ntsig ntawm ntau qhov kev sib tw ntawm DNA kuaj tau tawm cov txiaj ntsig tsis txaus ntseeg uas ua rau muaj lus nug txog seb qhov kev iab liam liam los ntawm Hudson, tam sim no 48, tuaj yeem yog qhov tseeb. Lwm txoj kev ntsuam xyuas them los ntawm Hudson tus qub hluas nkauj ntev ntev, Danita Metko, thiab nws tus txiv, Gene, tab tom pib.
Ib nrab kaum tawm tus kws tshaj lij DNA tau sab laj los ntawm The Medill Justice Project thiab los ntawm Hudson tus kws lij choj hais tias qhov tshwm sim nyuaj piav qhia.
Cov lus sib liam ntawm cov pov thawj cog yog cov nqi ntau ntawm cov tub ceev xwm thiab kev foob txhaum cai uas tau teev muaj hauv cov ntawv thov rov taug xyuas dua los ntawm Hudson. Lawv suav nrog qhov khoob hauv tub ceev xwm xa cov kab xev ntawm cov neeg caum uas hais txog ib rab riam uas tsis muaj; zaum thib ob vial ntawm cov neeg raug tsim txom cov ntshav coj mus thaum kuaj lub cev uas tsis kuaj rau; thiab qhov kev hais lus txhaum cai uas cov tub ceev xwm hais yog Hudson cov kev ua yeeb yaj kiab lees txim, uas yog tus kws tshuaj xyuas cov kab xev tau hais tias yuav tsis yog lam tau lam ua. Hudson tau hais tias nws tsis lees txim.
Tub ceev xwm kuj tseem ua tim khawv tias lawv pom rab riam Remington tua hauv Hudson lub tsheb thauj khoom - txawm tias lawv cov ntawv sau qhia tsis sib haum txog seb nws nyob ntawm tus neeg caij tsheb lossis tus tsav tsheb sab pem teb. Hudson DNA tsis pom ntawm riam thiab, nws cov kws lij choj tau foob, tsis yog nws tus ntiv tes. Hudson tau liam tias tub ceev xwm tshem tawm cov riam uas tseem nyob hauv nws lub ntim ntawm qab nws lub rooj zaum thiab cog rau hauv pem teb, qee lub sijhawm tau txhuam nws nrog Van Dyn Hoven cov ntshav.
Tus kws lij choj qub Outagamie County Koog Tsev Kawm Ntawv Tus Kws Lij Choj Carrie Schneider, uas tuav rooj plaub ntawm kev rov hais dua, tam sim no yog tus kws txiav txim plaub Outagamie County Circuit Court. Nws tsis kam qhia ntxiv. Biskupic, tus uas tam sim no zaum ntawm Outagamie County lub rooj ntev zaum, tsis yeem tawm tswv yim, xam tias txoj cai Lub Tsev Hais Plaub Siab uas feem ntau txwv cov kws txiav txim plaub tsis hais txog cov teeb meem tseem tos.
Cov kws lij choj tau foob cov kev liam tias ua txhaum cai ntau "ludicrous."
Hauv kev xam phaj rau zaj dab neeg no, ob tug neeg tim khawv uas pom Hudson ua ntej nws raug ntes thiab tom qab Van Dyn Hoven raug nyiag deev - Carnot thiab Kaukauna tus neeg nyob hauv Matthew Brittnacher - hais tias lawv tsis nco qab pom ntshav ntawm Hudson. Ob qho tseem ceeb ntxiv, txawm li cas los xij, lawv tsis tau tshawb nrhiav ntshav. Thiab Brittnacher hais tias nws qhov kev xav ntawm Hudson yog los ntawm "kev deb heev." Carnot thiab Brittnacher hais tias lawv muaj tseeb Hudson muaj txhaum.
Brittnacher hais rau Medill Qhov Kev Ncaj Ncees Project, "Nws muaj ntau tus neeg tsis muaj txim hauv tsev loj cuj, tab sis nws tsis yog ib qho ntawm cov neeg no."
Cov ntaub ntawv ua pov thawj ua txhaum
Cov lus nug txog cov pov thawj ntshav tau dhau mus ncig ntawm rooj plaub.
Hudson thiab nws tus kws lij choj tau tshawb pom tias cov kws tshuaj ntsuam pom tsis muaj ntshav rau ntawm lub kauj tsheb, lub iav hloov lossis tus neeg tsav tsheb sab pem teb hauv Hudson lub tsheb thauj khoom, txawm hais tias nws sab tes xis thiab sab laug ceg tau tawg liab ploog thiab riam pom nyob hauv pem teb. Thiab txawm hais tias Hudson nres thaum lub sij hawm nrhiav kom tsis tau lub nkoj los ntawm nws lub tsheb - ib qho xwm txheej pom los ntawm Brittnacher - tus kws tshuaj ntsuam pom tias tsis muaj ntshav ntawm lub thawb lossis nkoj.
Hauv kev hais plaub tom qab kev txiav txim siab, Hudson ua tim khawv hais tias nws qhib nws lub qhov rooj tsheb thauj khoom mus rau Van Dyn Hoven, uas tom qab ntawd nws zaum los ntshav rau ntawm tus neeg caij nrog mus tsuas yog khiav ceev ceev thaum nws pom Carnot tawm hauv ntoo los. Xav tias Carnot tau los tawm tsam nws, Hudson ua tim khawv tias nws nto qaub ncaug, ntaus nws lub tsheb thauj khoom.
Xyoo 2000, tus kws tshuaj xyuas Wisconsin State Crime Laboratory tau pom qhov mob liab nyob ntawm Hudson sab laug ko tsis yog tib neeg cov ntshav. Nws pom DNA los ntawm Hudson thiab Van Dyn Hoven ntawm nws sab tes xis.
Tus kws tshuaj xyuas, John Ertl, ua tim khawv rau Hudson xyoo 2001 kev tua neeg uas nws tau xaiv los sim ua qauv ntawm Hudson tus taw laug vim "nws zoo nkaus li ci ntsa iab, thiab nws zoo li muaj ntshav ntau nyob ntawd."
Ertl pom tias tsis muaj neeg DNA.
Ertl ua tim khawv hais tias "Qhov ntawd ua rau tsis yog tib neeg cov ntshav,"
Qhov tseeb, nws tau hais tias, tsis muaj tib neeg DNA tshawb pom nyob hauv ob txoj kev kuaj ntshav los ntawm Hudson sab laug ko taw.
Xyoo 2003, Ertl hloov nws zaj lus tim khawv, hais teb rau Hudson qhov kev thov rau DNA kuaj pom tias ntshav pom ntawm Hudson sab laug txhais taw yog tib neeg tab sis nws tsis tuaj yeem kuaj ib qho DNA hauv nws. Lub xeev tom qab lawv rov qab nws tus kheej, hais hauv 2004 tias muaj tsiaj ntshav pom ntawm Hudson thiab nws tuaj yeem tau los ntawm cov ntses uas nws ntes tau thaum nws mus pw hav zoov.
Thiab txawm hais tias cov duab ua pov thawj pom tias Hudson tau tawg los ntawm qhov uas pom tias yog ntshav, kev soj qab taug qab xyoo 2005 pom tias tsis muaj DNA nyob hauv cov qauv los ntawm Hudson sab tes xis - qhov twg Ertl nyuam qhuav dhau los kuaj pom Hudson thiab Van Dyn Hoven cov DNA.
Ertl tsis teb rau ntau qhov kev thov nrhiav cov lus pom txog qhov teebmeem tsis sib haum, uas nws tus kheej tau piav qhia hauv tsev hais plaub li “Txawv.”
Thaum Lub Ib Hlis, Outagamie County Circuit Judge Gregory Gill tau tso cai kuaj ntxiv tom qab tus kws lij choj kws lij choj Steve Miller tau sib cav hais tias cov tshuaj pom ntawm Hudson tau ua txhaum nrog - lossis tsis tseem muaj ntshav.
Hudson tus tom qab kev txhaum kev tawm suab rau kev kuaj DNA nrhiav kev tshawb pom yog tias cov qauv ntawm nws sab laug ko taw thiab sab tes xis muaj neeg cov ntshav lossis tsiaj, thiab seb puas muaj ib yam khoom dab tsi ntxiv rau qhov hnoos qeev uas yuav ua rau cov DNA tsis zoo.
Yog tias tsis yog tib neeg cov ntshav, nws yog dab tsi?
Nyob rau hauv cov lus tsa suab rau kev sim tshiab, Miller sau ntawv tias nws tau sab laj nrog Joan Gulliksen ntawm Cellmark Laboratories thiab Stephen Erickson ntawm LabCorp., Uas nws tau sab laj nrog lwm tus hauv kev teb.
Nws tau sau tias "Lawv thiab lawv cov npoj yaig pom qhov tsis muaj cov DNA rho tawm tsis tau nyob rau hauv cov xwm txheej no vim tias cov ntshav tshiab no muaj cov khoom siv DNA zoo,"
Hauv kev xam phaj, Miller tau hais txawm tias muaj ntau qhov kev sim ntawm kev sim, lub hauv paus ntawm cov tshuaj liab pom ntawm Hudson tseem yog qhov tsis meej.
“Puas yog tib neeg ntshav?” Miller tau nug. “Yog tias nws yog tib neeg cov ntshav, nws puas kis tau? Yog tias nws tsis txawm ntshav, nws yog dabtsi?
"Kuv xav tias txawm li cas los xij, yog tias peb tau txais txiaj ntsig tshwm sim los ntawm tib neeg cov ntshav thiab nws yog, koj paub, kis mus rau qhov chaw tsis muaj DNA hauv nws, lossis nws tsis muaj ntshav txhua, uas yuav cuam tshuam cov pov thawj rau Ken thiab nws tseem yuav corroborate nws tus account tias cov ntshav tau nyob rau hauv qhov tseeb tau nchuav rau nws - uas yog qhov uas nws tau liam txij thaum chiv keeb los. Vim tias yuav tsis muaj lwm qhov kev piav qhia. "
Tsis meej pem cov txiaj ntsig sai cov lus nug
Cov kws tshaj lij tau tawm tswv yim los ntawm Medill Qhov Ncaj Ncees Project ntawm Northwestern University tau zoo sib xws los ntawm cov kev ntsuas tsis raug raws cai.
Hauv kev xam phaj rau zaj dab neeg no, David Foran, tus thawj coj ntawm Forensic Science Graduate Program ntawm Michigan State University thiab University of Forensic Biology Laboratory, tau hais tias ib qho kev xav yog DNA kuaj los ntawm lub xeev kev ua txhaum kev ua haujlwm tau ploj mus lub sijhawm.
Tab sis tau muab lub sijhawm luv luv ntawm Hudson raug ntes thiab thaum kuaj tau coj - txog ob thiab ib nrab teev - nws tsis zoo li lub DNA yuav puas ua ntej ua ntej kev teeb tsa thawj zaug. "Nws yuav nyuaj rau ua txhua yam rau cov ntshav, tib neeg cov ntshav, hauv ob teev yuav tua tag nrho cov DNA zoo li ntawd," Foran tau hais.
Yog tias ib tug neeg tau ntxiv cov tshuaj phem uas muaj kuab lom xws li tshuaj ntxuav kom dawb, Ertl yuav tuaj yeem tshawb pom nws los ntawm qhov hloov pauv hauv cov ntshav hauv ntshav, Foran tau hais.
"Raws li nws tau hais hauv nws cov lus tim khawv, uas feem ntau yuav hloov tsos ntawm cov ntshav thiab," Foran tau hais. “… Kuv tabtom kwv yees nws yuav dhau mus. Ntau heev. ”
Them rau hauv cov ntshav?
Outagamie Lub Tsev Tub Ceev Xwm Hauv Nroog Sgt. Daniel Pamenter raug xa mus los yees duab qhov chaw ntawm Hudson raug ntes li 15 feeb tom qab kev caum tau hla hauv Appleton, raws li nws daim ntawv qhia tub ceev xwm. Pamenter tau thaij duab Hudson pw hauv tub ceev xwm lub tsheb, sau cia tus nqi luam ntshav ntawm nws lub cev.
"Hudson tau thaij duab thaum nws pw saum lub rooj thiab nws ob txhais ko taw tau raug thaij vim yog qhov uas pom tias tau ziab ntshav ... ntawm nws ob txhais ceg thiab txhais taw, thiab qee yam ntawm nws txhais tes, lub plab thiab hauv siab," Pamenter sau hauv nws cov lus qhia tub ceev xwm Cov.
Tom qab Hudson raug coj mus rau hauv tsev kho mob St. Elizabeth hauv Appleton, Pamenter thiab Kaukauna tub ceev xwm Don Krueger tau sau cov qauv DNA nyob rau hauv dab tsi yog xam tias yog cov txheej txheem ib txwm muaj, siv cov ntaub qhwv cov paj rwb thiab daim ntaub plaub-inch.
Ib qho ntxiv rau Hudson sab lauj taw, Ertl kuaj cov hnoos qeev los ntawm tus raug liam sab tes, sab taw xis thiab sab laug hauv siab - thiab peb txhua tus pom muaj cov ntshav. Cov kev ntsuas no, txawm li cas los xij, tsis raug kuaj rau DNA.
Cov ntaub ntawv qhia tias Ertl tsis muaj peev xwm suav cov tib neeg DNA los ntawm cov qauv coj los ntawm Hudson tus taw laug laug, cov ntaub ntawv qhia. Muab qhov tseem ceeb ntawm qhov tshwm sim rau cov ntshav, Foran tau hais tias, nws yog qhov txawv tsis pom tias tsis muaj tib neeg DNA.
Foran tau hais tias "Qhov ntawd ua rau me lossis tsis muaj kev nkag siab,"
Ashley Hall, tus pab xibfwb ntawm biopharmaceutical sciences ntawm University of Illinois ntawm Chicago, tau hais tias cov DNA yuav tuaj yeem ua paug lossis tsis huv ua ntej cov qauv coj mus kuaj, txawm hais tias cov ntshav muaj feem txuam nrog.
Hall hais tias, "Muaj ntau yam sib txawv uas tuaj yeem mus ua txhaum," Hall hais. Txhua yam haujlwm uas Hudson tau koom nrog tuaj yeem cuam tshuam nrog kev kuaj DNA, nws hais.
Hall hais tias, "Hauv kev xyaum, (kuaj DNA) tsis ua haujlwm zoo li peb xav," Hall hais.
Raws li Hudson hais, nws tau siv sijhawm ze li ob teev nyob rau ntawm txhais tes tom qab tub rog lub tsheb tom qab raug tub ceev xwm ntes. Nws hais tias nws tau khiav tawm ntawm qhov xwm txheej tua neeg vim tias nws tau ncua daim ntawv tsav tsheb thiab ntawv xas hauv nws lub tsev.
Tom qab nws raug ntes, Hudson - uas tau haus Valium thiab haus dej cawv thiab haus lub lauj kaub - tau hais tias nws tau pw tsaug zog thiab sawv mus rau qhov xav tsis meej.
“Kuv tau pw tsaug zog nyob tom qab ntawm pawg tub cheev xwm. Hudson ua tim khawv hauv ib lub rooj sib hais tom qab 2003 kev ua txhaum cai. “Thiab thaum kuv sawv, nws yog tus tub ceev xwm uas muaj lub khob. Thiab nws tau muab ntshav nog rau kuv txhais ceg, thiab kuv hais tias, 'Tsum qhov no. Koj ua dabtsi? '”
Hudson hais tias nws tau ncaws lub khob tawm ntawm tus tub ceev xwm txhais tes. Nws ua tim khawv cov tub ceev xwm ces tsiv nws mus rau lwm pawg tub rog lub tsheb, thiab zaum no ob tug tub ceev xwm qhib lub qhov rooj. Nws ua tim khawv hais tias ib tug tub ceev xwm hais rau nws tias, “Kuv yuav daws koj txoj sia me ntsis’ thiab lawv tau ntsiag to nrog kuv txhais tes rov qab rau ntawd. Thiab tom qab ntawd nws tau muab daim phuam thiab so kuv lub ntsej muag… Tom qab ntawd nws tau muab kuv lub siab dua li ob peb zaug. Tom qab ntawv kuv pib tawm tsam. "
Nyob rau hauv cov lus tsa suab tom qab kev txhaum, Hudson liam tias nws yog Kaukauna Tub Ceev Xwm Sgt. Robert Patschke, tus tub ceev xwm uas nyuam qhuav pib coj tus nees mus, uas tau hliv ntshav rau nws. Nws tsis tuaj yeem txheeb xyuas lwm ob tus tub ceev xwm.
Patschke tsis kam ua tswv yim, hais tias rooj plaub no muaj 17 xyoo yog "tus kheej" thaum nws paub tus neeg raug tsim txom tsev neeg.
Qhov tshwm sim ntawm sab tes sab xis
Tom qab Hudson raug ntes, Lub Xeev Txoj Kev Ntsuas Kev Ua Phem kuj tau sim ib qho piv txwv los ntawm qhov uas pom tau tias qhuav ntshav ntawm Hudson sab tes xis.
Hauv xyoo 2001 cov lus pov thawj, Ertl, tus kws tshuaj xyuas DNA, tau hais tias nws thawj zaug kuaj tshuaj los txiav txim seb tus qauv puas yog ntshav thiab tom qab ntawd tau tshawb xyuas qhov hnoos qeev nrog qhov uas paub tias polymerase saw cov tshuaj tiv thaiv thiab luv luv rov kuaj dua.
Lub luv luv hais rov qab pab ua kom paub qhov txawv ntawm ib tug neeg cov DNA los ntawm lwm tus thiab polymerase cov tshuaj tiv thaiv kev tsim cov ntawv theej ntawm DNA los tsim cov khoom siv ntau dua mus kuaj. Xav tau cov ntawv luam vim qhov ntau thiab tsawg cov qauv me. Qhov tshwm sim: Ertl pom Van Dyn Hoven's thiab Hudson cov DNA ntawm nws sab tes xis
Xyoo 2005, Ertl ua tim khawv hais tias nws kuj tau khiav ib qho kev sim tshwj xeeb ntau dua uas muaj npe hu ua ABAcard HemaTrace test siv los kuaj yog tias cov hnoos qeev los ntawm sab tes xis, ko taw sab laug thiab ko taw sab xis yog tib neeg cov ntshav los ntawm kev txheeb xyuas qhov muaj cov protein nyob hauv. Tag nrho peb qhov kuaj tau zoo rau tib neeg cov ntshav, nws hais.
Tab sis xyoo 2001, Ertl tau ua tim khawv cov qauv ntawm ko taw laug tsis yog tib neeg cov ntshav. Hudson tau hais hauv kev xam phaj hauv tsev hais plaub tias nws tus kws lij choj npaj yuav nce qhov kev tsis sib xws hauv tsev hais plaub.
Hauv xyoo 2005, tom qab sim los ntawm kev tiv thaiv los mus txiav txim lub hom tsiaj, Irving Kornfield, tsev kawm qib siab University of Maine tus kws tshaj lij thiab forensics, pom tsis muaj tsiaj lossis tib neeg DNA los ntawm cov qauv uas tau los ntawm Hudson sab tes xis. Kornfield tuag lub Plaub Hlis. Hauv lwm cov piv txwv, Kornfield tau pom tib neeg DNA - ib qho DNA raws qib uas phim Hudson thiab lwm tus muaj feem rau nws los ntawm nws niam mus tom qab ntau tiam neeg.
Ertl ua tim khawv tias ib qho laj thawj Maine lab pom tsis muaj DNA nyob hauv qee qhov qauv yog tias ib tug neeg ntxiv cov tshuaj tiv thaiv kab mob rau cov qauv lossis muaj qee cov pa paug, zoo li muaj cov roj teeb acid, tshuaj khesic lossis cov tshuaj ntsev ntau, xws li cov ntxhia tso nyiaj.
Ertl tau hais tias "Kuv tsis paub xyov puas muaj cov tshuaj tiv thaiv nyob rau qhov ntawd - tab sis qhov ntawd yuav yog qhov kuv xav tau zoo tshaj plaws uas yog vim li cas kuv thiaj tuaj yeem nrhiav nws siv cov txheej txheem tsis muaj suab nrov qhov uas lawv tsis tuaj yeem paub nws siv cov txheej txheem nthuav dav" “Lwm qhov kev piav qhia tej zaum yog kuv muab ib qho txiav los ntawm rab ntaws. Lawv tau coj mus txiav lwm qhov txawv ntawm qhov nt ntawd. Qhov ntau npaum li cas ntawm DNA ntawm ob qhov kev txiav ntawd yuav zoo sib txawv. "
Ertl tau sau tseg, txawm li cas los xij, tias Kornfield tau siv ntau dua cov kev sim uas muaj feem cuam tshuam nrog dab tsi yog hu ua mitochondrial DNA thiab yog li DNA yuav tsum tau kuaj pom hauv qhov piv txwv.
Theodore Kessis, tus tsim ntawm Applied DNA Resources, tus kws tshaj lij Columbus, Ohio tau tshawb xyuas tshwj xeeb hauv kev txheeb xyuas kev tshuaj ntsuam DNA tau hais txog, "Dr. Kornfield qhov kev sim rau (mitochondrial) DNA yog qhov kev txiav txim siab ntau dua li cov tshuaj tua hluav taws xob nuclear… sim siv rau Xeev Lub Xeev Qhov Kev Ua Haujlwm Loj tau siv. Thaum tib neeg lub cell muaj tsuas yog ob daim qauv ntawm nuclear los yog chromosomal DNA, tib lub cell muaj 1000's (sic) ntawm (mitochondrial) DNA uas yooj yim dua rau ntes tau. "
Hauv nws cov lus pov thawj xyoo 2005, Ertl tau hais tias nws muaj peev xwm ua tau cov tshuaj tiv thaiv tau ntxiv rau tus qauv. Nws hais tias ib qho tshuaj twg uas yuav cuam tshuam rau DNA kuj tseem yuav cuam tshuam cov protein nyob hauv ntshav, tejzaum nws hloov nws qhov tsos.
Nws tau hais lus pov thawj tias "(I) fwm tias DNA yog xim liab uas ci ntsa iab rau ntawm cov paj ntoo, Kuv xav tias yuav yog tus neeg sib tw zoo kom tau txais DNA los ntawm," nws ua tim khawv. "Kuv tau coj cov ntshav hla mus rau qhov muag dub lossis ntsuab lossis muaj pwm zuj zus tuaj rau lawv thiab kuv tseem tuaj yeem tau txais DNA los ntawm lawv. Tab sis cov ntawd yog cov cuam tshuam ntau dua ntawm lub sijhawm thiab kev ua roj ntsha. Ua rau kuv tsis paub tseeb tias cov tshuaj tua mob rau DNA yuav cuam tshuam licas rau cov ntshav. "
Kessis tau hais tias qhov kev piav qhia feem ntau yog qhov piv txwv tau qoj ib ce thaum nyob hauv kev khaws cia. "Kuv tau pom ntau tus neeg hauv cov DNA lwg me me tau ua rau lub sijhawm tsawg dua (tsawg)." Nws hais ntxiv hais tias qhov kev mob xeb zuj zus tuaj yeem yog vim huab cua lossis qhov kub nyob hauv chaw cia khoom.
Kev kuaj mob, ntsuas yuav tuaj yeem tuaj yeem tau
Innocence Project hauv New York tau sau tseg ntau qhov xwm txheej uas cov neeg tsis muaj txim raug rau txim vim kev kuaj DNA tsis raug. Kev sim DNA tom qab kev txhaum tawm kuj tau tsim cov pov thawj uas ua pov thawj.
Xyoo 1996, piv txwv, Marlon Pendleton raug txim vim yog kev quab yuam deev thiab tub sab nyob hauv Chicago. Ib pawg tub ceev xwm kev ua txhaum Chicago tub ceev xwm tau hais lub sijhawm ntawd tias tsis muaj pov thawj txaus rau kev kuaj DNA tau.
Tab sis yuav luag ib xyoo kaum xyoo tom qab ntawd, Lub Tsev Hais Plaub Ntawm Txoj Kev Txiav Txim Siab Tsis Txaus Ntseeg ntawm Northwestern University Tsev Kawm Ntawv Txoj Cai tau npaj rau kev sib tw zaum thib ob ntawm DNA ntawm tib qho pov thawj. Kev ntsuam xyuas, uas ua tiav rau qhov paum ntawm qhov paum uas tau txais los ntawm tus neeg raug tsim txom, tsis suav Pendleton ua tus ua txhaum.
Xyoo 1999, Josiah Sutton tau raug txim vim yog mos mos, thiab Houston Police Department Crime Laboratory tau hais tias cov phev los ntawm cov neeg raug tsim txom muaj Sutton DNA. Ob tus neeg sau xov xwm hauv zos, uas tau sau cov lus tseem ceeb ntawm cov tub ceev xwm kev ua txhaum kev tshawb nrhiav qhov tseeb, tau xa Sutton cov lus ceeb toom rau William Thompson, tus xibfwb qhia txog kev ntseeg ntawm University of California-Irvine, uas tau txiav txim siab tias lub chaw kuaj tsis raug. Lub phev tsis tau los ntawm Sutton.
"Raws li kev kuaj pom, nws pom tias cov txheej txheem ua haujlwm los ntawm HPD Serology / DNA Unit nyob rau hauv rooj plaub no poob qis dua kev lees paub tus qauv rau kev ua haujlwm tshawb fawb tau zoo," Thompson sau hauv nws tshuaj xyuas.
Kev soj ntsuam pom cov teeb meem thoob plaws ntawm lub chaw kuaj ib ncua los ntawm kev txhais tsis raug ntawm cov ntaub ntawv mus rau qhov uas tsis muaj ntaub ntawv, thiab tub ceev xwm fab tub ceev xwm raug tshem tawm DNA kuaj, raws li daim ntawv tshaj tawm zaum kawg los ntawm kev tshawb nrhiav ywj siab. Sutton tau tsa tawm rau xyoo 2004.
Hauv kev xam phaj rau zaj dab neeg no, Rena Xian, tus pab xibfwb ntawm cov kws tshawb fawb molecular pathology thiab hematopathology ntawm University of California-Los Angeles, tau hais tias muaj ntau yam tuaj yeem mus rau hauv qhov kev kuaj DNA.
“Kev kuaj DNA tsis yog txheej txheem ua tsis tiav; tsis muaj dab tsi, ”Xian hais. “Ntau yam muaj peev xwm mus tsis ncaj ncees lawm nyob ntawm txoj kev los sis qhov ntau npaum li cas ntawm DNA khaws cia. Yog tias muaj tsawg heev, nws yuav tsis txaus thiab qhov nyiaj yuav qis dua qib uas yuav tsum muaj rau kev ntsuas, yog tias kuaj pom tias ua rau nws rov qab los. "
Nws sau hauv email ntxiv, "Kev paug, yog tias tam sim no, feem ntau tshwm sim ua ntej cov qauv tuaj hauv chav kuaj."
