Dalton Michael Stone, 25, was shot and killed on Tuesday, September 4, 2018, in the 3000 block of Broadway Street in New Orleans. Emergency responders pronounced him dead at the scene after he suffered multiple gunshot wounds. The killing followed a series of altercations earlier that day that began with an argument between Stone and 21-year-old Brayanta Ketchens.

Investigators say Ketchens’ boyfriend, Devin Anderson, is alleged to have shot Stone. New Orleans Police Homicide detectives later identified 25-year-old Robert Lavigne as the perpetrator in Dalton Stone’s death; the Orleans Parish District Attorney’s Office indicted Lavigne on one count of second-degree murder while he was in custody in Jefferson Parish for a parole violation. Anderson was arrested in Florida and charged with one count of attempted second-degree murder in connection with the initial shooting of Stone.

The violence did not end with Dalton Stone’s death. In its aftermath, a group of men, including Dalton’s brother Jonathan Stone, are accused of breaking into Ketchens’ home and fatally shooting her; Jonathan Stone and Kenneth Murdock were arrested on second-degree murder charges, and additional suspects have been identified. If anyone has information about Dalton, the events of September 4, 2018, or the people involved, please share what is known.
