A manager of the bakery outlet, who declined to be identified Monday, said they didn’t know much about the incident but confirmed a verbal altercation had taken place.

A gunman opened fire at two locations last week, killing 18 people in the worst massacre in Maine’s history. He then kept the entire state on edge for two full days before he, too, was found dead of a self-inflicted gunshot wound. One nightmare is over, but the recovery has only begun.
