CLEVELAND, Ohio -- A teenage girl accidentally shot her 16-year-old sister Friday after pointing the gun she thought wasn't loaded at her friends, according to police.

A 15-year-old boy, who gave the girl the gun, is charged with possessing a weapon under disability. He pleaded not guilty Monday at his arraignment in Cuyahoga County Juvenile Court.

The shooting happened about 2:30 p.m. Friday in the bedroom at a home on Nathaniel Road, just south of St. Clair Avenue in the city's Collinwood neighborhood.

The girl told police that the 15-year-old boy handed her 16-year-old sister the gun, police reports say. The 16-year-old girl handed it to her younger sister. She said she knew it was real, but thought it was unloaded, police reports say.

The girl waved the gun around and pointed it at some of the four other people inside the home, according to police. One of the other girls said, "Don't point that gun at me," police reports say.

The girl turned, pointed the gun at her older sister and shot her in the right shoulder, according to police. The girls' mother was on the phone at the time of the shooting, police reports say.

The girl was taken to University Hospitals, where she was treated and released.

The 15-year-old boy hid the gun after the shooting in bushes on the side of the home, police reports say. He was initially uncooperative with police, but eventually showed them where he hid the gun, police reports say.

The teen was ordered detained at the Cuyahoga County Juvenile Detention Center. He was on probation after being convicted of rape in October 2017, court records say.
