Aderrien Murry, 11, called 911 for help at his home in Indianola, Miss., last weekend. But after police arrived, an officer shot him in the chest. The boy is recovering, but his family is asking for answers — and they want the officer involved to be fired.

Aderrien’s mother, Nakala Murry, says she told her son to call her mother and the police after the father of one of her other children appeared at their house in the early hours of Saturday, May 20. She was concerned for her safety, Murry said — but when police arrived, things went terribly wrong. An officer ordered people out of the home, and then shot Aderrien after he left his room, she said.

Her son doesn’t understand what happened, Murry said. “His words to me were: ‘Why did he shoot me? What did I do?’ and he just started crying,” 

The Mississippi Bureau of Investigation is investigating the shooting, in which it says a minor “received significant injuries.” The agency provided few details in response to a request from NPR, citing the ongoing gathering of evidence.

Several Indianola officials, including Mayor Ken Featherstone, did not respond to NPR requests for comment about the shooting incident.
