Four Idaho police officers who fatally shot an autistic, nonverbal teenage boy who was holding a knife on the other side of a chain-link fence in April were justified in their actions and will not face criminal charges, according to the state attorney general.

A California law firm notified the city of Pocatello, Idaho, of its intention to file a federal wrongful death lawsuit on behalf of the family of Victor Perez, a 17-year-old boy with intellectual disabilities who was shot multiple times by four police officers.

A teenage boy described by his family as autistic, nonverbal and intellectually disabled remains in critical condition after being shot in his backyard by Idaho police last weekend.
