A man from New Hampshire, previously convicted for the brutal murder of his father, now faces new allegations involving the abuse and strangulation of his mother, as reported by the police.

Forty-year-old Ian Delmore has been charged with “assault – domestic violence – strangulation” and “domestic violence – simple assault.” These charges stem from accusations of attacking and abusing his mother, according to a report from the local NBC affiliate WBTS.

Delmore’s mother contacted the authorities, expressing fear for her safety and informing them that she had been assaulted by her son. Following this, officers arrived on the scene and detained Delmore after speaking with her.

The investigation that followed gathered sufficient evidence leading to the formal charges against him.

In a previous incident, local ABC affiliate WMUR reported speaking with Delmore’s mother after his 2007 arrest. At that time, Delmore was apprehended for the murder of his father, which occurred following a dispute over a home improvement project.

“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,” the mom said.

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.
