Barron Thomas Grumbling was 21 when he was shot and killed in Johnstown, Pennsylvania, on May 1, 2017. The shooting took place around 10 p.m. in the West End; a 911 caller testified to hearing three gunshots and seeing two Black men in red hoodies running from the scene. Grumbling was a Johnstown resident and a graduate of Johnstown High School. He was born May 22, 1995, in Niagara Falls, New York.

Investigators initially arrested Daekwon Coleman after finding him in the area with a revolver, but DNA evidence later excluded him as the shooter and he was charged with conspiracy to commit homicide. Detectives shifted focus to 16-year-old Mizzon Unique Grandinetti, who was later found guilty of first-degree murder at a June 2022 retrial. Grandinetti was convicted for shooting Grumbling at close range; he is serving a life sentence without parole. Barron’s memorial was at Harris Funeral Home and he was cremated by Laurel Highland Crematory.
