Barking Dogs May Have Sparked Phoenix Family Slaying. 5 Humans And 2 Dogs Dead

A makeshift memorial has been set up in front of the Moore home on Monday Oct. 28, 2013, in Phoenix, to remember the four shooting victims. Police say loud barking dogs might have led to 56-year-old Michael Guzzo, to kill four of his neighbors and the neighbors' two dogs before turning the gun on himself, and dying. The victims were identified as Bruce Moore, 66; his daughter, Renee Moore, 36; her husband, Michael Moore, 42, who took his wife's name; and Renee's son, Shannon Moore, 17. (AP Photo/Ross D.

Phoenix • For months, Michael Guzzo complained to neighbors about incessant dog barking, even putting up fliers on doors throughout his Phoenix townhome complex advising people of pet ordinances and fines.

This weekend, police say, Guzzo went on a rampage, methodically killing four members of a family and their two dogs that lived next door before killing himself with the same shotgun.

While his motive died along with him, neighbors and family members of the victims say he was becoming increasingly unhinged over dog noise.

Neighbors in the complex of two-story townhomes said Guzzo made no secret that the barking dogs were irritating him.

He often left printouts of the city’s dog-barking ordinance on doors throughout the community, said Joni Flood, 21, who lives a few doors down from the victims.

"He hated them. But everyone here has dogs," Flood said.

Killed in the Saturday shooting were Bruce Moore, 66; his daughter, Renee Moore, 36; her husband, Michael Moore, 42, who used his wife’s last name; and Renee’s son, Shannon Moore, 17.

Family members of the victim were in shock Monday as they walked into the crime scene for the first time, standing amid pools of drying blood on the home’s back patio where the two men were apparently killed first.

"It’s angering beyond belief," said Patrick Riley, 41, Michael Moore’s brother. He found his brother’s silver necklace amid the blood. "It just angers me looking at all this because I just feel for my brother. The helplessness."

The patio wall was chipped with pockmarks from the shotgun’s blast. Police haven’t given specific details of the attack, but Riley said he thinks Guzzo shot his brother over a 6-foot cinderblock fence while he worked on a car engine.
