Remy, 35, was sentenced Tuesday to life in state prison without the possibility of parole after changing his plea to guilty after he was charged with the August 2013 stabbing death of Martel, 27.
"Jared Remy perceived that he was losing control of Jennifer Martel and lashed out at her in a fit of rage, killing her," Middlesex District Attorney Marian Ryan said in a statement. "Today, with this plea, the defendant has been held accountable for his actions. This plea ensures that Jared Remy will spend the rest of his natural life in prison."
The gruesome details of the case rippled through the small community of Waltham, Massachusetts, after questions surfaced about why Remy had not been held on bail after his arrest just two days before the slaying.
Remy was arrested on August 13 for assault and battery after Martel told police that Remy had grabbed her neck and head and "slammed her face against a mirror" in the bathroom during an argument, according to a Waltham police report.
Martel fled the home with the couple's daughter to a neighbor's home and called 911.
Martel could be heard on the call, which was released by police, saying "(Remy) is just a very violent person who is on lots of medication who might need serious help."
