An Ottsville man will serve prison time for stabbing his girlfriend’s ex-partner and later threatening him during a phone call from prison.

Jeremie Hammerstone, 30, was sentenced to three to six years earlier this week after he plead guilty to aggravated assault, retaliation against a witness, terroristic threats and possession of an instrument of crime.

Hammerstone was at the home of his girlfriend, Heather Radcliffe, on June 23, 2017, when Karl Kennedy, Radcliffe’s former partner, arrived. Radcliffe and Kennedy had an altercation outside, then Kennedy entered the home and got into a scuffle with Hammerstone. Hammerstone subsequently stabbed Kennedy in the left side with a knife after the fight escalated into the bathroom. Kennedy then drove himself to the Doylestown Hospital for treatment, and the state police were notified.

Hammerstone made things worse for himself a few months later, when he made a threatening phone call to Kennedy from the Bucks County Correctional Facility. Hammerstone was awaiting trial at the time, when he convinced a female friend to set up a phone call during which he told Kennedy, “You’re (expletive) dead.”

Kennedy notified the police once again, saying he feared for his safety and that of his children.

Following his prison term, Hammerstone will serve two consecutive years of probation. The sentence is a result of a plea deal between Deputy District Attorney Thomas C. Gannon and Deputy Public Defender Suzette S. Adler.

“You acted out, and your behavior is inexcusable,” Judge Wallace H. Bateman Jr. said to Hammerstone. “You know that.”

Hammerstone told Bateman that he is on medication for depression and anxiety. Hammerstone also has a history of methamphetamine use.

“I’m sorry, sincerely sorry to the court and to my victims,” Hammerstone said. “I want today to be remembered not as a waste of time, but as a turning [point] in my life.”
