Arizona gunman kills neighbors, dogs

PHOENIX — Authorities released details Sunday from a weekend shooting 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 Saturday that may have been touched off by loud barking, police said.

Phoenix police Sergeant Tommy Thompson said there is ‘‘some indication that perhaps that was a problem.’’ He added, because of the deaths, a motive may never be known.

The victims have been identified as Bruce Moore, 66; his daughter, Renee, 36; her husband, who took his wife’s name, Michael Moore, 42; and Renee’s son, Shannon, 17.

After the killings, Guzzo shot at another townhouse before returning to his unit and killing himself, police said.

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.

A neighbor said Guzzo kept to himself. ‘‘I’ve seen him every morning — come in quiet every morning,’’ Donald McKenzie told KSAZ-TV.

After shooting the Moores and the dogs, Guzzo then walked across the complex and shot at the door of another townhouse, police said. No one was injured at that home.
