Chase Costello, 22, was fatally shot on June 23, 2023, near Mexia, Texas. Deputies say they responded to reports of two vehicles chasing and shooting at each other on Highway 84 just west of Mexia. Before officers arrived, one vehicle left the road and stopped in a pasture; deputies found Costello deceased and a 20-year-old passenger, Joseph Raheem Smith, seriously injured and later airlifted in critical condition. The other vehicle involved fled the scene before law enforcement arrived.

The Limestone County Sheriff’s Office opened a homicide investigation. As of the latest reporting, no arrests have been made and no suspects have been publicly identified. Costello’s family held a balloon release on July 1, 2023, and his obituary notes he was born February 2, 2001, in Baytown and was a father to a daughter named Aurora and an unborn son. Anyone with information is asked to contact the Limestone County Sheriff’s Office or Limestone County Crime Stoppers.
