In a disturbing case from New Hampshire, a man previously convicted of fatally stabbing his father is now facing charges for allegedly assaulting and strangling his mother, according to police reports.

Ian Delmore, aged 40, has been formally charged with “assault – domestic violence – strangulation” and “domestic violence – simple assault” following the recent incident. This information comes from local NBC affiliate WBTS.

The police received a call from Delmore’s mother, who reported being attacked by her son and expressed fear for her safety. Officers responded swiftly to the scene and detained Delmore after interviewing his mother.

A subsequent investigation gathered sufficient evidence to formally charge him with the alleged crimes.

Reports from local ABC affiliate WMUR recall Delmore’s 2007 arrest for his father’s murder, which reportedly occurred following a dispute over a home renovation project.

Despite the circumstances, Delmore’s mother expressed gratitude, saying, “I would like to commend the Nashua Police Department for their care and their professionalism, and I would like to tell my son that I love him very much.”

Delmore was 22 years old when he pleaded guilty to second-degree murder in 2008 for killing his dad. Prosecutors said he was arguing with his mom over a plumbing project after she purchased a wrong part when his dad stepped in and began fighting with him, according to the Associated Press.

“You brought this on yourself,” Delmore told his father during the stabbing attack, according to prosecutors. “You drove me to it… It’s all your fault,” Delmore said.

After the slaying, Delmore stabbed himself in the chest and abdomen before running over to a neighbor’s house to ask for help. He was hiding in the woods, covered in blood, when police found him, the AP reported.

“I know I’m going to jail,” Delmore told cops. “I need help. I’m hurt.”

Delmore reportedly planned to claim self-defense at his murder trial before accepting a plea deal, per the AP. He was also going to bring up his mental health history and claim that his father abused him.

“I’d like to take this opportunity to apologize to my family, and my mother, for the pain and the loss that I have caused through my actions, and I am very sorry for what happened,” Delmore said at his sentencing, during which he was ordered to spend 25 years behind bars, according to reports.

Delmore, however, was released from prison early in May.

He is being held without bail, awaiting his next court date.
