The 3-year-old cousin to a Washington pro football player died last Sunday after accidentally shooting himself in the head at a home in Katy, authorities said.

The child, Radyn Terrell, found the gun in a bedroom at his family’s home in the 28200 block of South Firethorne Road and shot himself, police said. He was airlifted to a nearby hospital and died around 4 p.m. Sunday, according to Fort Bend County Sheriff’s Office spokesman Major Chad Norvell.

Norvell identified the child as a relative to Derrius Guice, a Louisiana native who in 2018 joined the NFL team as a running back.
