Os investigadores que usaram um site genealógico para encontrar o ex-policial que eles acreditam ser um assassino em série sombrio e estuprador que aterrorizou a Califórnia décadas atrás, consideram a técnica inovadora.
Mas outros dizem que isso levanta preocupações legais e de privacidade preocupantes para os milhões de pessoas que enviam seu DNA a esses locais para descobrir seu patrimônio.
Não existem leis de privacidade rígidas para impedir a polícia de vasculhar os bancos de dados de sites de ancestrais, disse Steve Mercer, o procurador-chefe da divisão forense do Gabinete do Defensor Público de Maryland.
"Pessoas que enviam DNA para testes de ancestrais estão se tornando informantes genéticos em sua família inocente, sem querer, "Mercer disse, acrescentando que eles "têm menos proteções de privacidade do que criminosos condenados cujo DNA está contido em bancos de dados regulamentados."
Joseph James DeAngelo, 72, foi preso na terça-feira depois que investigadores compararam o DNA da cena do crime com o material genético armazenado por um parente distante em um site online. De lá, eles reduziram para o avô da área de Sacramento usando DNA obtido de material que ele descartou, A promotora distrital do condado de Sacramento, Anne Marie Schubert, disse.
As autoridades se recusaram a nomear o site online. Contudo, dois dos maiores, Ancestry.com e 23andMe, disse quinta-feira que não estavam envolvidos no caso.

O DNA potencialmente pode ter desempenhado um papel anterior no caso. Estava começando a ser usado como ferramenta de investigação criminal em 1986, quando o predador conhecido como o Estuprador da Área Leste e o Assassino do Golden State aparentemente encerrou sua onda de ataques de uma década.
DeAngelo, um ex-policial, provavelmente saberia sobre o novo método, especialistas disseram.
"Ele conhecia as técnicas policiais, "disse Louis Schlesinger, professor do John Jay College of Criminal Justice." Ele era inteligente. "
Ninguém que conheceu DeAngelo ao longo das décadas o conectou com a sequência de pelo menos uma dúzia de assassinatos, 50 estupros e dezenas de roubos de 1976 a 1986 em todo o estado.

Depois que ele foi identificado como o suspeito, Contudo, os promotores correram para acusá-lo de oito assassinatos.
Além disso, A polícia da cidade agrícola de Visalia, no centro da Califórnia, disse na quinta-feira que DeAngelo é suspeito do 13º assassinato e de cerca de 100 assaltos na área.
Em 1975, do professor de faculdade comunitária Claude Snelling foi baleado enquanto tentava impedir um intruso mascarado de sequestrar sua filha de 16 anos de sua casa.
Os investigadores não tinham evidências de DNA, então a morte de Snelling e os roubos não foram incluídos na contagem de crimes do Assassino do Golden State, mas impressões digitais e rastros de sapatos serão revisados para encontrar DeAngelo, Disse o chefe da polícia de Visalia, Jason Salazar.

Os investigadores revistaram a casa de DeAngelo na quinta-feira, procurando anéis de classe, brincos, pratos e outros itens que foram retirados das cenas do crime, bem como armas.
Enquanto isso, Vizinhos de DeAngelo, parentes e antigos conhecidos, todos dizem que não tinham a menor idéia de que ele poderia ser um assassino em série. Ele trabalhou quase três décadas em um armazém de supermercado na área de Sacramento como mecânico de caminhões, aposentando-se no ano passado. Como um vizinho, ele era conhecido por cuidar meticulosamente de seu gramado nos subúrbios de Citrus Heights.
DeAngelo trabalhava como policial na cidade agrícola de Exeter, não muito longe de Visalia, de 1973 a 1976.
DeAngelo era uma "ovelha negra" que não brincava com outros oficiais, disse Farrel Ward, 75, que serviu na força com DeAngelo.

Ward disse que é possível que DeAngelo tenha ajudado na busca pelo assassino de Snelling e pelo ladrão indescritível, mas ele não se lembra de DeAngelo investigando diretamente o assassinato.
"Eu estive a pensar, mas não há nenhuma indicação de que algo estava errado, " Ward said. "How could you just go out and kill somebody and go back and go to work? I don't understand that."
Mais tarde, DeAngelo joined the Auburn Police Department outside of Sacramento but was fired in 1979 after he was caught shoplifting a hammer and dog repellant.
Investigators say they have linked DeAngelo to 11 killings that occurred after he was fired.

James Huddle said he always hoped police would catch the killer whose attacks prompted him to buy a pistol.
But he was stunned to find out the man arrested was DeAngelo, his former brother-in-law.
Huddle said it was "still just going crazy in my mind."

A look at DNA testing that ID'd a suspected serial killer
Joseph James DeAngelo, who authorities suspect is the so-called Golden State Killer responsible for at least a dozen murders and 50 rapes in the 1970s and 80s, was arrested more than three decades after the last killing with the help of information from an online genealogical site. Investigators haven't disclosed many key elements about how and why they took this very unusual step to find a suspect.
Here's a look at the case and some of the questions surrounding it:
HOW DID AUTHORITIES IDENTIFY HIM?
The Sacramento County district attorney's office said Thursday DNA from one of the crime scenes was checked against genetic profiles from genealogical websites that collect DNA samples to help people learn about their family backgrounds.
Authorities zeroed in on DeAngelo after determining one of his relatives whose genetic information was on the site was a familial match for the DNA from the crime scene.
They then set up surveillance at DeAngelo's home in Citrus Heights, Califórnia, just outside Sacramento and collected two "discarded DNA samples" from him. One didn't contain enough DNA but the other tied him to the DNA evidence.
Authorities did not identify the DNA websites that were used.
___
IS THAT LEGAL?
Ancestry.com and 23andMe, two of the largest companies that produce genetic profiles for customers who provide DNA samples, say they don't cooperate with law enforcement unless they receive a court order.
Both said Thursday they did not receive a court order in the DeAngelo case and were not otherwise involved.
Ancestry.com has said it hasn't received any such requests for genetic information in the last three years.
A 23andMe spokesman said the company "has never given customer information to law enforcement officials" and that their platform doesn't allow for the comparison of genetic data that was processed by any third party.
___
HAS THIS EVER BEEN DONE BEFORE?
The issue of law enforcement comparing DNA to samples in genealogical databases garnered national attention several years ago when a New Orleans filmmaker was identified in an Idaho murder based on a DNA sample that his father had given years earlier.
As part of a church-sponsored genealogy project, the man's father had provided his DNA, which was later sold to Ancestry.com.
The company was required to identify the man to police after receiving a court order. But he was eventually cleared after his DNA didn't match the evidence at the crime scene.
___
WHAT IS THE DNA TEST THAT INVESTIGATORS USED IN THAT CASE?
The technique is known as familial DNA testing and it has raised ethical issues in the forensics community. Typically with the method, investigators search law enforcement databases to identify likely relatives of the person who may have committed the crime.
Critics say that familial DNA testing allows for searches of innocent people who happen to be related to someone suspected of committing a crime or otherwise provided their DNA for inclusion in a database. Law enforcement officials have argued the technique can provide investigators with valuable leads.
Em 2008, California became the first state in the country to authorize the testing. It since has been used in at least eight other states.
The method led to the arrest of Lonnie Franklin Jr. in the Los Angeles "Grim Sleeper" serial killings from 1985 to 2007. Los Angeles County sheriff's officials also used it last year to solve the decades-old killing of the ex-wife of Righteous Brothers singer Bill Medley.
