US killer may have acted after romantic dispute

THE off-duty sheriff’s deputy who killed six young people and critically wounded another during a homecoming weekend gathering may have acted following a romantic dispute.

Tyler Peterson, 20, was shot to death by police after opening fire early on Sunday at a home where, authorities said, the friends met for pizza and movies.

He was off-duty from his full-time job as a Forest County deputy sheriff; he also was a part-time Crandon police officer.
