Terence Tyler, who allegedly shot and killed two co-workers and himself in the New Jersey supermarket where he worked on Friday, published a tweet three years ago that read, "is it normal to want to kill ALL of ur coworkers?" Tyler, who left the Marines in California soon after, began working at the supermarket recently. The 23-year-old, who was wearing desert camouflage gear when he allegedly opened fire on the Pathmark store in Old Bridge Township, was discharged from the armed forces when he showed signs of depression. Family members say he never got over his mother's death five years ago.
