Authorities released details today from a weekend shooting attack that left four family members and two dogs dead at a central Phoenix townhouse before the gunman turned the weapon on himself. Michael Guzzo, 56, killed his next door neighbors in a deadly confrontation yesterday that may have been touched off by loud barking, police say. Phoenix police Sgt. Tommy Thompson says there is "some indication that perhaps that was a problem." But he added that because of the deaths, a motive may never be known.
The victims have been identified as Bruce Moore, 66; his daughter, Renee Moore, 36; her husband, who took his wife's name, Michael Moore, 42; and Renee's son, Shannon Moore, 17. After the killings, Guzzo shot at another townhouse before returning to his unit and killing himself, police say. Police said they found a pump shotgun, apparently the weapon used in the killings, next to his body. Thompson said there was no indication he had a violent past. (Read more shooting stories.)
