We’re cooperating with all investigations," the company said in a statement. It could not comment further citing the ongoing investigation. "It's Amazon's responsibility to verify the worthiness of the vehicles being used to deliver their products, we believe there was negligent hiring," Garcia said.

"No amount of money will bring back a grandmother or a mother, but at least there would be some closure for the family," Garcia said.
