Authorities charged a fourth person in the fatal shooting of a Michigan security guard who had refused to let a customer inside a store without a face mask. The prosecutor says Brya Bishop's alleged crimes occurred after the death of áCalvin Munerlyn. Munerlyn was shot last Friday at a Family Dollar near downtown Flint. Bishop is charged with tampering with evidence, lying to police and being an accessory to a felony. Bishop is the sister of a man who is still at large in the guard's death.
