A 19-year-old man shot and killed a younger teen on Sunday when they and two other friends were “horseplaying” with a gun they hadn’t checked to see if it was loaded.

The Menifee Police Department responded to the call at about 8:30 p.m. and said that Jesse Duncan pulled the trigger, shooting a 17-year-old in the abdomen, the Press-Enterprise reported.

All four of the teens stayed on the scene and called 911, police said. The other two teens were 18 and 17, KMIR reported.

“A preliminary investigation revealed the four of them were horseplaying with the firearm,” Menifee Police Capt. Dave Gutierrez said. “While horseplaying, and believing the firearm was not loaded, (Duncan) pulled the trigger, striking the victim in the upper torso. Duncan and the other two teenagers immediately called for help.”

The victim died at the scene, he said.

Duncan was charged with involuntary manslaughter and released on a $25,000 bond. He is due in court on May 2, according to Riverside County jail records.

The victim’s identity was not immediately released.
