The case of Nathan Carman, a Vermont man who was accused of murdering his mother off the Rhode Island coast in 2016, is returning to television on “20/20” this week.

The true crime investigation show announced it will be premiering the new special, “Family Lies,” on Friday.

Carman, who was from Vernon, was charged with first-degree murder and fraud in the death of his mother, 54-year-old Linda Carman, on a fishing trip. She was never seen again and is presumed dead.

In 2023, Carman died by suicide in jail while awaiting trial.

“20/20” said its special on the Carman case, “Family Lies,” will premiere Friday, April 4 at 9 p.m. ET.

According to a trailer posted on social media, the episode will feature never before seen police interrogation videos as well as new details and interviews about the case.

The episode will also discuss the death of Carman’s grandfather, John Chakalos. A wealthy real estate developer, Chakalos was shot at his home in Connecticut in 2013. Carman was never charged in the case, though an indictment accused him of the killing in an effort to defraud insurance companies.

Nathan Carman was interviewed on ’20/20′ before

Six years before his death, Carman appeared on “20/20” to deny the claims against him.

On the 2017 episode, Carman also alleged that police officers targeted him in his grandfather’s death because he had Asperger’s syndrome.

At one point when questioned about whether he sabotaged his boat to make it sink, he abruptly left the interview before returning 20 minutes later.
