ALBUQUERQUE, N.M. (KRQE) – Diazien Hossencofft is behind one of the most bizarre and infamous murder cases in Albuquerque. In 1999, he killed his ex-wife, Girly. To this day, her body has not been found.

Now, decades later, he’s asking that his plea and life sentence be thrown out.

“Society views murder as the most heinous crime known to mankind. Like when you decide you’re going to commit murder, you decide you’re going to trade life for theirs. I did that,” said Hossencofft in 2002.

His testimony is hard to forget.

“She knew she was going to be hunted like the dog she was, and yes, she ran like a scared rabbit in an open field. She knew,” he continued.

That’s how Hossencofft talked about the murder of his ex-wife Girly Chew Hossencofft. He confessed, and plead guilty. He’s currently serving a life sentence.

Now, 18 years later, he’s asking a judge to vacate his sentence. In more than 400 pages, he makes claims and provides pages of interviews and evidence.

The biggest claims are that his sentence was illegal, he was denied due process because of collusion, his attorneys failed at their jobs, and he was forced into his plea deal.

Hossencofft claims prosecutors were colluding with Albuquerque Police to hide evidence that would’ve exonerated him and his mistress, Linda Henning. Henning is also serving time in prison for the murder.

During a hearing in court Thursday, Hossencofft’s attorney asked Judge Alisa Hart for more time to get his facts organized.

Judge Hart: “And you absolutely feel like you need six months?”

Attorney John McCall: “I do, your honor. I don’t want to give too many details, but this case involves global connections.”

Judge Hart granted that six-month extension. This case is so intriguing, it’s been the focus of countless books, articles, and news segments.

Henning is currently serving time here in New Mexico. Officials won’t say where Hossencofft is for safety reasons.
