Using Familial DNA for leads to Crimes
Quote | Reply
I don't have a problem with the concept of using publicly available DNA to search for criminals. I think it only points them towards a pool of possible perpetrators and they have to then gather evidence to link them to the crime.

Could Familial DNA Crack Case of Slain New York City Jogger?

With a DNA profile but no suspect to match in the strangling of a woman who went for a run and met a killer, authorities are looking to an emerging approach: using the DNA to look for the killer's relatives.

The technique, known as familial DNA searching, has made inroads in some U.S. states and other countries in the last decade, leading to both high-profile arrests and civil-liberties qualms.

Now, New York state officials plan to discuss Friday whether to introduce it after a request from prosecutors and police yearning for a lead in the case of 30-year-old runner Karina Vetrano.

Authorities see the technique as a powerful, precise investigative tool. And to Vetrano's family, the case for the search is clear.

"Our only goal in life is to find out who did this to our daughter," said her mother, Cathy Vetrano. "So if there's any method available to do that, we want it done."

But critics view the technique as a DNA dragnet that can single out otherwise law-abiding people for scrutiny because of family ties.

"A policy that implicates New Yorkers in a criminal investigation solely because they are related to someone with DNA in the state's databank is a miscarriage of justice," said Donna Lieberman, the New York Civil Liberties Union's executive director.

Ten states, including California, Texas and Florida, conduct familial DNA testing. Ohio on Monday announced its first effort yielded an arrest in the kidnapping and rape of a 6-year-old girl and the attempted abduction of a 10-year-old girl.

But at least two jurisdictions, Maryland and the District of Columbia, have prohibited the practice.

Authorities have long worked to identify suspects by matching crime scene evidence to convicted offenders' DNA. Familial DNA testing goes further, seeking people similar enough to be closely related to whoever left the crime scene DNA.

Investigators can then explore whether such people have family members who fits as suspects. If so, they need other evidence, possibly a match to a suspect's own DNA, to bring charges.

Familial DNA famously led to an arrest in Los Angeles' "Grim Sleeper" serial killings, which spanned from 1985 to 2007. Lonnie Franklin Jr. was convicted and sentenced to death this year.

After Vetrano's beaten body was found Aug. 2 in a marshy park in her quiet Queens neighborhood, investigators developed a DNA profile of the probable attacker from material under Vetrano's fingernails and on her neck and phone, but it didn't match anyone in law enforcement DNA databases.

Meanwhile, police chased down 85 tips, interviewed runners, looked for clues in Vetrano's personal life and examined surveillance video and even panhandling reports from areas nearby.

"This tragic murder has been exhaustively investigated using every tool currently available," Queens District Attorney Richard Brown said Thursday in asking the state Commission on Forensic Science to authorize familial searching.

Commissioners intend to discuss the topic at a meeting Friday. It's not clear when or what they'll decide, but spokeswoman Janine Kava said Thursday they'll continue working to provide law enforcement with "cutting-edge tools" to solve crimes "without compromising individual protections."

Concerns about familial DNA searching hit home for New Orleans filmmaker Michael Usry in 2014, when police showed up with a warrant to get his DNA as a possible suspect in a 1996 killing in Idaho.

A crime scene DNA sample was similar to that of Usry's father, who'd voluntarily given it for a nonprofit genealogy project; police had gotten the data from a website that acquired it. The baffled filmmaker spent a month worrying about what would happen before further testing cleared him.
"It was a very weird situation," he said earlier this year.

Cases like his trouble the technique's critics. So does the idea of training an investigative lens on offenders in law enforcement databases to scrutinize relations with clean records.

"We don't subject some people to disparate treatment because of taint of blood," says Erin Murphy, a New York University law professor who has studied the issue. "It's a violation of some of our foundational principles."

Supporters say familial DNA investigations can be structured to pursue only strong leads and do it discreetly. California, for instance, strives to investigate them without letting on to the potential suspects or their family members.

"The idea that we're rousting relatives, innocent people, it's a fabrication," says Rockne Harmon, a retired California prosecutor and prominent voice for familial DNA searching.

Cathy Vetrano has her own assessment. "If any person who thinks it's unfair was in this situation," she says, "I think they would be feeling differently."

I guess it depends on how wide the pool is. I think private companies like 23 and me should be off limits. But if they have a familial link via a prisoner and can narrow it to a direct family member maybe. But if they start going for cousins. Nephews and nieces. No way. Too wide. If I get asked for DNA because my cousin. Fuck you.

You'll climb the wrist-thick kudzu vines that wrap the Sears Towers. And when you look down, you'll see tiny figures pounding corn, laying stripes of venison on the empty car pool lane of some abandoned superhighway." T Durden

This is probably not the future of solving crimes. That will be microbial cloud matching and they most certainly wont need a warrant to get yours. They'll just walk up behind you in public and collect it. Match it to the scene of the crime and boom.

I think they are using the crininal DNA databanks not private ones. I say fill your boots... if its a close hit you should be able to narrow the investigation.

It means, "go ahead, be my guest." I think it comes from bull fights. It's like telling a matador, "Ok buddy, if you want to get in there with a pissed off bull, be my guest. Fill your boots." I.e. Fill them with the blood that will be dripping once you get gored.

I'm not really sure how big a deal this is. Police search for suspects and people to interview based on all sorts of associations. If they're using DNA databases that are already otherwise available to them, it seems like a fairly reasonable technique.

What if they were looking at a family and investigating everyone except that one person who hasn't been told that they are adopted. Then that person finds out?

Cool? Not cool?

As long as they call that person a waaah-mbulance before hand, I say cool.

Maybe not cool, but not cool doesn't mean illegal or unconstitutional. Not cool is allowing someone to grow up to adulthood without telling them they were adopted.

What happens when they can then take this a step further and can ID the guys race? (Or enough racial DNA markers)

Seems possible based on just the consumer products alone.

Ignoring the biological debate about the existence of race....Identifying race by dna alone is not so simple.
