The Old Bridge, New Jersey, Pathmark shooting in which three people -- including gunman Terrence Tyler -- died on Friday morning was tweeted by the disturbed 23-year-old former Marine in advance, as early as in 2009 and beyond, reported the AP.
Then disturbed Marine, stationed in California, Terence Tyler, tweeted three years ago on: "is it normal to want to kill ALL of ur coworkers?"
Authorities are investigating his motive, but family members said Tyler was discharged from the Marines two years ago after suffering from depression and had never gotten over his mother's death about five years ago.
Tyler left his job as an overnight clerk at the Pathmark about 3:30 a.m. He drove off and returned to the store shortly afterward with a handgun and an assault rifle. About a dozen workers were in the closed store at the moment.
Tyler fired more than 16 rounds from his rifle — shooting at an employee standing outside and blowing out windows. He also shot at five other workers in an aisle, killing Christina LoBrutto, 18, and Bryan Breen, 24.
Tyler, who began working at the supermarket less than two weeks ago, then drew his handgun and killed himself. Several ammunition magazines were recovered along with the rifle and a .45-caliber handgun.
Some of Tyler's disturbing tweets:
"smh is it normal to want to kill ALL of ur coworkers?Maybe but I'm actually in a position where I can,smh," he wrote in June 2009, using the handle (at)Tylerbkstyle and the abbreviation "smh" for "shaking my head."
"I'm starting to see why plp go on killin sprees," he wrote. And these (obscenity) are reeeeeeally pushin my kill everyone I see button."
