Donald Armstrong Jr., 23, of Miami Gardens was killed on June 23, 2018, in a daylight ambush under the Palmetto Expressway overpass. Armstrong and another young man, Stephen Campbell, were inside an SUV when a shooter opened fire. Campbell was pronounced dead at the scene; Armstrong was taken to Ryder Trauma Center and later died of his wounds.

Witnesses described the suspect as a young Black man in his twenties, thin, about 5 feet 7 inches to 5 feet 8 inches tall, last seen wearing tan or beige shirt and pants and fleeing north on Northwest 27th Avenue. The Miami Gardens Police Department launched an intensive investigation and appealed to the community for information, but the case initially remained unsolved, leaving family members grieving and fearful.

Does anyone have information about that day under the Palmetto Expressway overpass or remember seeing someone matching that description near Northwest 27th Avenue?
