From his own backyard and home in the background, it is believed that this is where Michael Guzzo began his shooting rampage with a shotgun over a shared wall and into the backyard of the Moore home on Monday Oct. 28, 2013, in Phoenix. 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.
