Price Motel crime scene

Police investigators work the crime scene at the Price Motel on East North Street on March 8.

A judge ordered a $500,000 cash-only bond Monday for the Rapid City man charged in last week’s fatal stabbing in which a mother of six children was stabbed 40 times at a local motel.

Vincent Mousseaux, 23, is facing charges of first-degree murder and an alternative of second-degree murder in the killing of Deziree Martinez, 30. She was found dead Wednesday in a room at the Price Motel on East North Street.

At the Pennington County Courthouse on Monday morning, a prosecutor asked Magistrate Judge Scott Bogue for a $500,000 cash bond, saying Mousseaux had stabbed Martinez 40 times after breaking the motel room windows.

Authorities say he also tried to stab another man during the incident; Mousseaux faces additional charges of aggravated assault in that attack.

First-degree murder is punishable by death or life imprisonment, second-degree murder by life and aggravated assault by up to 15 years in prison. Mousseaux can be convicted of only one of his alternative charges.

Mousseaux appeared in court via video link from the county jail. He was dressed in a red-striped uniform, indicating he has been segregated from the general inmate population.

A lawyer assisting him had asked the judge for a lower bond, explaining that Mousseaux was not a flight risk since he had family in Rapid City.

The lawyer said Mousseaux has anxiety problems, for which he is taking medication, and has been experiencing "physical problems" in jail.

His alleged crimes, she said, are believed to be alcohol related, and his previous charges did not involve violence.

In February, Mousseaux received probation and a suspended jail sentence on a local burglary-related charge. In January, he also received a suspended jail sentence for violating a protection order against a woman.

Late Tuesday evening, according to Rapid City police, Martinez, Mousseaux and another person were in a room at the Price Motel at 401 E. North St. when an argument broke out.

Mousseaux tried to stab Martinez with a knife when the third person, whom police did not identify, stepped in to defend Martinez. Mousseaux then tried to stab that person, but the person grabbed the knife from him.

Mousseaux grabbed another knife, chased the person from the motel room and returned to stab Martinez multiple times, police said.

Mousseaux was arrested in Martinez's death Thursday, a day after police found her body at the motel. Mousseaux was then already in jail after being arrested due to a probation violation Wednesday morning, less than a mile southeast of the motel.

The police department said it did not receive any report of disturbances in the area of the motel between Tuesday evening and Wednesday morning.

On Thursday evening, the relatives and friends of Martinez gathered outside the motel for a candlelight vigil.

People offered prayers, sang “Amazing Grace” in English and Lakota and played traditional drum music, said Pastor Larry Salway of the He Sapa New Life church, who spoke at the gathering.

“Violence is very unnecessary, and yet people who are under the influence of mind-altering substances, they are becoming very violent,” Salway told the Journal. “You can see in the deaths in the last three, four months, it’s so unnecessary.”

Martinez is the fourth known homicide victim in Rapid City this year.
