A man who killed four members of a
neighboring family and their two dogs with a shotgun before
taking his own life over the weekend in Arizona may have been
sent into a rage by the dogs' barking, police said on Sunday.
But police said what drove 56-year-old Michael Guzzo of
Phoenix to carry out the shooting frenzy may never be known for
certain, as both he and his victims, who ranged in age from 17
to 66 and lived next door, were dead before officers arrived.
"It appears he had some issues with barking dogs," said
spokesman Sergeant Tommy Thompson
. "If true, it
does not justify killing four people."
Police found the victims slain after responding to a report
of gunshots at about 9:15 a.m. on Saturday in a downtown
townhouse complex, Thompson said.
