LOS ANGELES (AP) — A 12-year-old boy who was shot in the head when a gun accidentally went off in the backpack of a classmate is experiencing impaired vision and has trouble walking as the bullet remains lodged in his head, his former teacher said Tuesday. The boy, Issa Al-Bayati, will require another surgery and months of treatment, Bridgette Robinson wrote in a post on a GoFundMe fundraising page for him. Robinson, who taught at Sal Castro Middle School for four years, said Issa is also having frequent bouts of dizziness.
