A single shooter turned a quiet Dover Township block into a crime scene when Gary Williams, 48, and his wife Tina, 46, were killed inside their home.

The violence reportedly started with Lutes confronting Dominick Galliano, whom Lutes had accused of assaulting a family member. Gary Williams had testified on Galliano’s behalf at that trial. Lutes is said to have shot and killed Dominick, his wife Gail, and their son Christopher at the Galliano residence. He then crossed the street and killed Gary and Tina Williams; the Williamses’ 23-year-old son escaped by jumping from a back window and flagged down police. Afterward Lutes drove to Barnegat, wounded his police chief, and then died by a self-inflicted gunshot.

What details about the neighborhood dispute or the lead-up to the shootings might help explain how this escalation happened, and can anyone who knew the families or witnessed events provide information?
