A 16-year-old was shot and killed Thursday in North Fort Worth while he and his friends passed a gun around, police said.

The teens were waiting in a car outside a home on North Elm Street when the gun went off around 9:12 p.m.

"At least one of the juveniles was not aware that the weapon was loaded, pulled the trigger, and struck the victim," police Sgt. Joe Loughman told the Fort Worth Star Telegram.

The victim, Jose Alvarez, was taken to John Peter Smith Hospital, where he was pronounced dead at 9:46 p.m., according to the Tarrant County medical examiner's office.

The shooting remains under investigation, and no arrests have been made. Police are still trying to determine how the juveniles came into possession of the gun.

Alvarez was a sophomore at Diamond Hill-Jarvis High School.
