"They were trying to kill me," Yolanda Aguilar's husband said. "My niece was living with this guy who used to do a lot of coke. He tried to get my son to help him sell some. We never do no coke or marijuana or nothing like that."

George Aguilar was the driver of of the vehicle from which the shots were fired, police said. Investigators have not said what role Adrian Aguilar played in the killing.
