Is there a simple list of proven facts on this person somewhere? I don't want to assume anything.
yes
his dad is an ex-sheriff
they are a mormon family
His mom and dad registered republican but he registered unaffiliated
the family loves guns and there is tons of pictures of them shooting guns together and giving them as gifts
possible military ties via uncle as some guns shooting suggest that with military humvee behind and that big gun but that could just be the shooting range
