A West Covina man accidentally shot his son-in-law while showing him a handgun Friday afternoon, police said.

The incident, which was being investigated as an accidental shooting, was reported about 4:40 p.m. at a home in the 900 block of South Russelee Drive, West Covina police Lt. Dennis Patton said.

A 9mm bullet penetrated a 28-year-old man’s wrist after the handgun, which his father-in-law was holding, discharged, the lieutenant said.

“He was reportedly showing a weapon to a relative when the weapon inadvertently went off,” Patton said.

Paramedics took the injured man to a hospital with an injury not considered to be life-threatening.

The men’s account of the shooting was corroborated by other witnesses at the scene, Patton added.

Police seized the involved gun, Patton said. Though it appeared the shooting was an accident, “We will do a comprehensive investigation.”
