There they found a man in the hallway who was stabbed multiple times, according to the report. He was pronounced dead at the scene. The victim was identified as Stewart Wayne Mousseaux Jr., 37, according to KELO.


Before he died, the victim told a neighbor that “it was Zach Dubrey” who stabbed him, the station reported. Police arrested Dubray the following day.

A 47-year-old woman was also stabbed several times and taken to the hospital for treatment.

Witnesses said the suspect knew the victims and they were drinking the day before.

Dubray was charged with first-degree murder, second-degree murder and several counts of aggravated assault.

He eventually took a deal, pleaded guilty to manslaughter and attempted murder in exchange for prosecutors dropping several charges, KELO reported.

Dubray was recently sentenced to serve life in prison.

"This sentence is a victory for victims," the Minnehaha County State’s Attorney said in a statement shared with KELO. "It should send a clear message to habitual criminals and violent offenders that law enforcement and prosecutors are committed to public safety. The Minnehaha County State’s Attorney’s Office will continue to work hard to ensure justice comes to all who commit such heinous acts."
