  • Police in Colorado have cracked the cold cases of four women killed 40 years ago.
  • Denver PD said genetic genealogy and DNA analysis helped them identify the serial killer.
  • He had died by suicide in jail in 1981. DNA from his exhumed body matched evidence from the murders.

Police in Colorado have cracked the code on four murder cases that went unsolved for 40 years, using DNA from the killer's exhumed body.

The cases pertain to four women killed in the Denver metro area between 1978 and 1981. They were 33-year-old Madeleine Furey-Livaudais, 53-year-old Dolores Barajas, 27-year-old Gwendolyn Harris, and 17-year-old Antoinette Parks. The four women were stabbed to death. Denver Police Commander Matt Clark said in a press conference Friday that there was an "underlying sexual component" to the murders but didn't elaborate further.

In 2009, a detective reviewed Parks' case and picked several pieces of evidence for potential DNA analysis. Most hadn't yet been subject to forensic DNA analysis, which wasn't an option in the 1980s. In 2011, another detective swabbed an empty glass tube that used to contain evidence, hoping to find trace residue, and was able to find the DNA profile of an unknown man. The man's profile was entered into a database and later linked to the three other women's cases.

Police began tracing genetic genealogy with the suspect's DNA in 2019 and found a positive ancestry link in Texas, the Denver Post reports. Their search for members of the suspect's family led them to a close biological relative.

Police identified Joe Michael Ervin as a suspect. Ervin had died by suicide in 1981 while in jail for the murder of an Aurora police officer. His remains were exhumed late last year, and DNA from his body matched the DNA profile of the male in the four cases.

One of Parks' brothers, George Journey, spoke at the press conference Friday, saying Parks' family has "closure" now that her killer has been identified.

"We can finally have peace knowing who did this to my little sister," Journey said.

Instagram accidentally reinstated Pornhub’s banned account

By
After years of on-and-off temporary suspensions, Instagram permanently banned Pornhub’s account in September. Then, for a short period of time this weekend, the account was reinstated. By Tuesday, it was permanently banned again. “This was done in error,” an Instagram spokesperson told TechCrunch. “As we’ve said previously, we permanently disabled this Instagram account for repeatedly violating our policies.” Instagram’s content guidelines prohibit  nudity and sexual solicitation . A Pornhub spokesperson told TechCrunch, though, that they believe the adult streaming platform’s account did not violate any guidelines. Instagram has not commented on the exact reasoning for the ban, or which policies the account violated. It’s worrying from a moderation perspective if a permanently banned Instagram account can accidentally get switched back on. Pornhub told TechCrunch that its account even received a notice from Instagram, stating that its ban had been a mistake (that message itse...

Watch Aidy Bryant *completely* lose it as 'SNL' roasts political pundits

By
On Saturday Night Live , there are breaks and then there's whatever happened here. The Season 45 premiere featured a sketch that was meant to expose the empty noisemaking of political punditry on TV. But part of the joke involved a series of quick costume changes, and some weirdness during one of those switches led to a complete and total breakdown. Aidy Bryant, the segment's host, couldn't take it. She manages to keep it together until what appears to be an accidental wide shot exposes some of the magic as we see a woman who's probably a member of the SNL wardrobe crew fiddling with Aidy's costume.

California Gov. Newsom vetoes bill SB 1047 that aims to prevent AI disasters

By
California Gov. Gavin Newsom has vetoed bill SB 1047, which aims to prevent bad actors from using AI to cause "critical harm" to humans. The California state assembly passed the legislation by a margin of 41-9 on August 28, but several organizations including the Chamber of Commerce had urged Newsom to veto the bill . In his veto message on Sept. 29, Newsom said the bill is "well-intentioned" but "does not take into account whether an Al system is deployed in high-risk environments, involves critical decision-making or the use of sensitive data. Instead, the bill applies stringent standards to even the most basic functions - so long as a large system deploys it."  SB 1047 would have made the developers of AI models liable for adopting safety protocols that would stop catastrophic uses of their technology. That includes preventive measures such as testing and outside risk assessment, as well as an "emergency stop" that would completely shut down...
