A Texas man who decapitated his wife just four months after their impromptu wedding was found dead in his prison cell on Friday.

Jared James Dicus, 24, pleaded guilty to the barbaric murder of his wife, 21-year-old Anggy Diaz, in an open-and-shut trial in 2024.

Dicus was sentenced to four decades in prison, and his earliest parole date was set for 2043.

On Friday, he was found hanging in his single-person cell at the Wainwright Unit in Houston County, according to a state death report obtained by KLTV.

Prison staff attempted life-saving efforts when they came across Dicus’ body, but he was pronounced dead by responding EMS staff just before 11 p.m., according to the report.

Diaz and Dicus wed in October 2022, much to the revulsion of their closest friends who disapproved of their rocky relationship.

Diaz’s mutilated corpse — including her severed head that was ditched in the shower with a knife — was found in the couple’s Houston-area home on Jan. 11, 2023.

Dicus’ father, who lived in a larger home on the same property as the couple’s cottage, came across Diaz’s body and immediately called the cops.

Dicus had a few hours to spare between the murder and his swift arrest. During that window, he cruised over to the Chepes meat market where Diaz worked and stole a can of beer, which he chugged in the parking lot, according to chilling surveillance footage.

A close friend of Diaz’s told The Post in 2023 that Dicus was seemingly insecure about his marriage.

“He posted a video saying, ‘She is mine,’ to social media, and it was weird because no one was questioning that….it was out of no where,” said the pal, who asked not to be named.

The friend said that she last saw Diaz at a Christmas party less than a month before she was killed.

Dicus was in attendance, but abruptly stormed out “looking really upset” while everyone else “was having a good time,” she said.

The pal said she suspected Diaz was a victim of domestic violence, even though “she never said there were any problems” and speculated “she was just embarrassed to admit her relationship wasn’t perfect.”

Her assumption was corroborated by local police.

Mere days after Diaz was killed, Waller County Sheriff Troy Guidry revealed that the department was aware of the couple. He noted that there were prior “disturbance” calls made, but nothing that matched the “level of violence” in Diaz’s gruesome murder.

Diaz, who started working as a fitness coach not long before her death, aspired to settle down and have children, but her friend advised that she “avoid getting pregnant so quickly” after tying the knot with Dicus.
