Store shooter was a ‘troubled employee’

A man who killed a manager and wounded two workers at a Long Island grocery store was a “troubled employee” who had been reprimanded in recent months for threatening and sexually harassing colleagues, police said Wednesday. Gabriel DeWitt Wilson, a shopping cart collector, opened fire Tuesday in an office area above the retail floor about 40 minutes after talking to a manager about transferring to another store, Nassau County Police Detective Sergeant Stephen Fitzpatrick said.
