Patrick Riley, brother of shooting victim Michael Moore, surveys the bloody crime scene for the first time at 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.
