PHOENIX (AP) - Authorities have started to release details from a weekend shooting attack that left four family members and two dogs dead in a Phoenix townhouse before the gunman turned the weapon on himself.
Police say 56-year-old Michael Guzzo killed his next door neighbors in a deadly confrontation that may have been touched off by loud barking.
Phoenix police Sgt. Tommy Thompson says Sunday that there is "some indication that perhaps that was a problem." But he adds that because of the deaths, a motive may never be known.
Police say the victims were 66-year-old Bruce Moore; his daughter, 36-year-old Renee Moore; her husband, 42-year-old Michael Moore; and Renee's son, 17-year-old Shannon Moore.
Police say Guzzo then shot at another townhouse before returning to his unit and killing himself.
