A community leader said that days before the shooting, the grandfather, Maximo Garcia, had turned himself in to police in an effort to clear his name, along with about a dozen accused drug users.

Garcia eventually returned to the family. The grandfather was later shot three times and injured, police said. He is in a hospital under police guard.
