GULFPORT, Miss. — Police on the Mississippi Gulf Coast say a 16-year-old boy accidentally shot himself while making a video displaying guns.

Gulfport police said Tuesday that Damien Thompson Jr. fatally shot himself in the chest Saturday with a handgun. He was pronounced dead at a hospital.

Police say two 15-year-old boys who were also participating took two handguns, a shotgun and a rifle outside the house and hid them. Officers later found the guns.

Both juveniles are charged in youth court with possession of a handgun by a minor and tampering with evidence. Police say the case will also be presented to a grand jury.

Thompson’s father, Damien Thompson Sr., was shot to death in Gulfport in 2013.

Gulfport Sgt. Clayton Fulks says police are investigating how the teens got the guns.
