PHOENIX (AP) - Family members of Michael Guzzo say he suffered for years from paranoia and depression, always refusing to seek help while blaming his troubles on others.
Guzzo 's internal fight with those demons culminated over the weekend when he shot to death four members of a family who lived next door to him, along with their two dogs, before turning the gun on himself at their central Phoenix townhome complex.
Authorities and neighbors speculate that the barking dogs possibly drove him to kill. But his ex-wife, Janet Guzzo, a retired behavioral nurse, says she saw warning signs long ago. She says he suffered from depression and paranoia but refused to seek treatment.
She always knew his life would end at his own hands, but she never suspected he would kill others.
