On the evening of July 12, 2021, a barrage of more than 30 shots rang out outside the Harmony Dwellings housing complex in Beaver Falls, Pennsylvania. The gunfire left 30-year-old Monte Warren and 31-year-old Dwayne Wells dead at the scene and wounded three other men.

Investigators identified Monte Warren’s brother, Decarlos Kavaun Warren, then 20, as a central figure connected to the confrontation. Authorities described Monte’s death as occurring during a subsequent gunfight and characterized it as self-defense, though the person who fired the fatal shot was not publicly named. An arrest warrant was issued for Decarlos, who had traveled from Michigan.

Decarlos Warren was located and arrested in Michigan in March 2023 and extradited to Beaver County on multiple charges, including criminal homicide, attempted homicide and aggravated assault. His trial produced a split verdict: acquitted of the murder charge in Dwayne Wells’ death but convicted of aggravated assault. He was sentenced to 5 to 10 years in prison.
