A security guard was shot and killed at a Family Dollar store in Flint, Michigan after asking a customer to wear a state-mandated face mask, police said.
Calvin Munerlyn, 43, died Friday at a local hospital after being shot in the head, Michigan State Police Lt. David Kaiser said.
Kaiser told CNN on Monday the gunman and a second suspect remain at large.
Witnesses at the store told police that Munerlyn got into a verbal argument with a woman because she didn’t wear a mask, prosecutor David Leyton told Genesee County. Video surveillance confirms the incident, Leyton said.
Under a Michigan Gov. Gretchen Whitmer executive order, all retail staff and customers are expected to wear a mask.
Footage also reveals the woman leaving in an SUV shortly after the altercation.
But the SUV returned about 20 minutes later.
Two men entered the store and one of them, Leyton said, screamed at Munerlyn for disrespecting his wife. The other man then shot the officer.
“This is ridiculous. Over a mask. Over a mask?” Tina James, cousin of Munerlyn, told CNN affiliate WJRT. “This is not the way things are going right now. We need to come together.” Family Dollar did not respond to a comment message.
