Michigan family charged with murdering security guard who said daughter had to wear a mask

A 43-year-old store security guard was fatally shot in the back of his head after he told a 45-year-old woman that her daughter could not enter the store without a face mask, reports BBC.

After the initial verbal altercation at the store, Genesee County Prosecutor David Leyton told a news conference on Monday, Sharmel Teague shouted at and spat on Mr Munerlyn before driving away in a red GMC Envoy.

She returned a short while later with her son and husband before the fatal confrontation ensued, according to officials.

It was the son who allegedly pulled the trigger.

The prosecutor told reporters: "The death of Calvin Munerlyn is senseless and tragic, and those responsible will be held accountable to the fullest extent of the law."
