Raise money for a P. I. to help find my Dad

In the middle of March I received a phone call from my brother asking if I had heard from my father in awhile and I said no. Come to find out my dad has vanished. He was last seen the first week of February by his landlords. He got in his van and drove off from his trailer. He left all his stuff and right now we do not have any leads as to where he may be. He is 59 and fighting depression due to his wife's death.

We are trying to raise money to hire a private investigator to follow through on the investigation. We have no idea where he is or even if he is still alive.

Any and all help would be greatly appreciated.
