Guilty plea entered in 2017 killing of 18-year-old Daphné Huard-Boudreault

There's been a guilty plea in the case of an 18-year-old South Shore woman whose killing sparked a conversation about how victims of conjugal violence are protected by authorities.

Anthony Pratte-Lops, 24, pleaded guilty to a charge of second-degree murder in connection with the death of his ex-girlfriend Daphné Huard-Boudreault in March of 2017, just days before a jury trial was to begin.

He had originally been charged with first-degree murder, and it's expected he'll now have to serve 18 years in prison before becoming eligible for parole.

Huard-Boudreault had ended their long-term relationship a week before her death. During that week, Pratte-Lops' behavior had worried her enough to seek police protection, fearing Pratte-Lops would turn violent.

On the day she died, March 22, 2017, Huard-Boudreault met with officers to ask for protection as she went to her ex-boyfriend's house to collect her things.

Even with a police escort following at a distance, however, Huard-Boudreault was stabbed the moment she entered the apartment. She was stabbed at least 15 times.

A later investigation from the Bureau of Independent Investigations clear the police escort of any wrongdoing.
