Rapid City, SD.  –    Twenty-four-year-old Vincent Mousseaux of Rapid City has been sentenced to 70 years in prison for fatally stabbing his 30-year-old roommate.

In March of 2017 Mousseaux stabbed his then roommate, and mother of six children, Deziree Martinez, following an argument. Martinez was said to have been stabbed 40 times. Late last year, Mousseaux pleaded guilty to first-degree manslaughter. Prosecutors were seeking a life sentence and say that the murder was aggressive and violent.

Mousseaux’s attorney cited that his client had mental health issues.

Mousseaux will become eligible for parole after serving 60 percent of his 70-year sentence.
