Loud barking may have caused a tragic shooting rampage that left two dogs and five people dead—four of them members of one family - and one believed to be the shooter. The massacre occurred in a central Phoenix condominium complex on Saturday morning, police said.
The victims were 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.
Police identified the suspected gunman as Michael Guzzo, 56, a next-door neighbor to the victims,
When police responded to the victims' home, they discovered two bodies on the patio and two inside, and two dead dogs with gunshot wounds, CBS affiliate KPHO reports.
Guzzo left the scene on foot and his body was found in his townhome next door, police told KPHO. He apparently died of self-inflicted gunshot wounds.
Police said they found a pump shotgun, which appeared to be the weapon used in the killings, next to his body.
After killing the family, Guzzo shot at another townhouse before returning to his unit and killing himself, police said. Libni DeLeon, a resident of the complex, told CNN affiliate KNXV that he heard a knock on his door and then a man started shooting through his front door. No one was hurt.
Phoenix police Sgt. Tommy Thompson said there was no indication Guzzo had a violent past.
Details provided to FOX 10 by Michael Guzzo’s ex-wife may provide a key to why he would shoot a family of four and their two dogs, although she said no explanation could excuse his actions.
Michael Guzzo was a pharmacist. His ex-wife, Janet, described him to FOX 10 as someone “who struggled with just about everything” and who had rage and anger problems.
She told the station, "He had…depression…he was paranoid, and I could see it getting worse throughout the years."
Janet described how Guzzo struggled to keep jobs and she was told he was so bothered by barking dogs at the complex that he would go around leaving angry notes on owners' doors. She told FOX 10 that something triggered his rage and Guzzo snapped on Saturday morning.
Sgt.Thompson said there is "some indication" that barking "perhaps was a problem." But he added that because of the deaths, a motive may never be known.
