Shalonda Mixon, who is the sister of Joe Mixon, was named as a suspect in the shooting that occurred at the Cincinnati Bengals running back's home.
TMZ Sports cited police documents and reported "several juveniles were playing a game called 'dart wars' near" the home on Monday night. Two of the game's participants told police a 16-year-old boy had a toy gun and was running alongside the house when shots were fired at him from Mixon's backyard.
One of the bullets struck the boy in the foot.
Police documents listed "unknown suspect(s)" as the shooter and said a black car left the home in the aftermath.
