Man drinks at parents house, gets into an accident with me, can I sue his parents home owners insurance for serving him alcohol?

Question Details: Person consumed alcohol at parents house and hit us in an auto accident. He was driving his father's car. They had auto insurance, but it was only 30K limit. My family's medical bills are well over 150K. I've conducted an asset search on his parents, they basically have nothing, and what they do have is protected by AZ law. I want to know if I can sue the parent's home owner's insurance policy since the son consumed alcohol on at their house before the accident? I have police reports to substantiate this claim.
