The latest court developments for the man suspected of fatally stabbing Deziree Martinez. STABBING DETAILS


Feb. 12, 2018

Vincent Mousseaux, 24, was sentenced to 70 years at the South Dakota State Penitentiary Monday for first-degree manslaughter.

On March 9, 2017, Mousseaux stabbed 30-year-old Deziree Martinez to death at the Price Motel on East North Street after an argument. Martinez was found with knife wounds on her face, chest, abdomen and lower extremities. There was blood splatter on the walls and ceiling.

Police say a third person was also in the motel room and attempted to stop Mousseaux by taking the knife away from him. Mousseaux then pulled out another knife, chasing that person out of the room.

According to the State's Attorney's Office, Mousseaux then turned around and re-entered the motel room. Police found him several hours later sitting outside a residence in the Robbinsdale neighborhood of Rapid City. His blood alcohol content was three times the legal limit.

Prosecutors say that during Mousseaux's 341 days in the Pennington County Jail, he assaulted a Pennington County deputy. Mousseaux pretended he was choking, causing the deputy to enter his cell. Mousseaux then hit the deputy and took his pepper spray, spraying the deputy.

Elizabeth Mousseaux, Vincent’s sister, also appeared in court to make a statement. She said her brother is "a very loving man” and has “struggled with alcohol addiction.”

She also spoke of his “neglectful and abusive childhood.”

Mousseaux will receive credit for his time already served. He will be released when he’s 93 years old.
