Three members of a Michigan family have been charged for killing a Family Dollar security guard who told one of their relatives that she wasn’t going to be served without a face mask.

Last month, Michigan Gov. Gretchen Whitmer passed an executive order that requires all retail employees and customers to wear a mask.

Calvin Munerlyn died at a Flint hospital after being shot in the head on Friday, CNN reported.

The 43-year-old got into a heated exchange with Sharmel Lashe Teague, 45, after telling her daughter that she needed a mask to be serviced by the store. According to Genesee County Prosecutor David Leyton, surveillance video confirms the incident.

"From all indications, Mr. Munerlyn was simply doing his job in upholding the Governor's Executive Order related to the COVID-19 pandemic for the safety of store employees and customers," Leyton said in a statement.

Teague's daughter eventually left the store, but not before Teague and Munerlyn engaged in a shouting match, which ended when he told her to leave the store and commanded a cashier not to serve her.

About 20 minutes after the initial altercation, surveillance footage shows the woman’s vehicle returning to the store’s location, according to CNN.

Then, Larry Edward Teague, Sharmel's 44-year-old husband, and Ramonyea Travon Bishop, her 23-year-old son, entered the store. Larry had words with Munerlyn about “disrespecting his wife,” Leyton said. Bishop then allegedly shot the security guard, the statement detailed.

Bishop, Larry and Sharmel were all charged with first-degree premeditated murder in Munerlyn's killing.

Munerlyn's devastated cousin told a local news outlet the killing was senseless.

"This is senseless. Over a mask. Over a mask? I don’t understand it," Tina James told WJRT.

Randy Guiler, vice president of investor relations at Dollar Tree, which acquired Family Dollar in 2014, said the company is aware of the altercation and is respecting the Munerlyn family's privacy.

"We will continue to cooperate fully with local authorities on their investigation," Guiler told CNN. "As always, we are committed to ensuring a safe environment for our associates and customers. Out of respect for the family's privacy, we are not commenting further at this time."

Sharmel is in custody and awaiting trial on her charges in court, but police are still searching for Larry and Bishop, CNN reported.

Bishop also faces a felony firearm charge and a charge of carrying a concealed weapon. Larry’s record includes two felony firearm-related charges, one charge of a felon in possession of a firearm, one charge of carrying a concealed weapon and one for violating the governor's executive order, according to CNN’s report.

In his statement, Leyton said Sharmel also faces a felony firearm charge and doesn't have legal representation at the moment.
