A 13-year-old boy died Tuesday afternoon after his friend shot him during "antics with the gun" in an apartment near 19th and Southern avenues, Phoenix police said

Police responded about 11:18 a.m. to a shooting at an apartment near the 5400 block of South 19th Avenue, where officers were initially told that the shooting was accidental and the boy shot himself, Sgt. Tommy Thompson said.

However, detectives learned that Arthur Miles, 13, was at a friend's home lying down in a bedroom when his 16-year-old friend entered the room with a handgun he had recently acquired, according to Thompson.

The 16-year-old "made admissions surrounding antics with the gun" which resulted in Miles being shot, Thompson said.

Miles was taken to a hospital in extremely critical condition where he later died.

The 16-year-old was detained at the Maricopa Juvenile Court Center, Thompson said.
