The gun was supposed to be empty, but an 18-year-old found out the hard way that it wasn't.
Now, San Antonio police are trying to figure out whether criminal charges are appropriate for what's being described as an accidental shooting.
Officers said they responded to a call for a shooting in the 400 block of Utopia around 12:30 a.m. Monday.
They found a teen shot in the stomach. He was taken to the San Antonio Military Medical Center.
The victim reportedly told investigators the shooting was an accident.
Police said a 19-year-old was showing off a 9mm handgun to two friends. The gun was supposed to be empty after the clip was pulled out. But there apparently was one bullet still inside the gun.
The 18-year-old victim, whose name has not been released, tells police he hit the trigger of the gun. That's when he was shot. The two others grabbed the gun and ran to another apartment on the premises.
Officers found the two hiding in the rear of an apartment unit. They also found the gun.
The two were being questioned in connection with the accidental shooting. Police believe the gun belongs to the 19-year-old. Criminal charges in this case are uncertain.
The 18-year-old is recovering at SAMMC. He's listed in critical but stable condition.
