WWII Veteran lost his wife and home

My father who is 88 and a veteran of WWII lost his wife of 50 years in September. His only asset was his home. Yesterday, on December 20, 2016, his entire home and car burnt to the ground, We found out yesterday that he had somehow cancelled his home insurance, leaving him penniless and hopeless. He is wanting to try to rebuild a tiny home but does not have any hope because every single thing he had in his life was destroyed in the fire. He is refusing to live with me and is trying to live in a shed where the house was because he is so distraught. I have been a schoolteachee for over two decades and have never asked anyone for help. I am desperately begging for any amount to show him that there is more than darkness to life. I honestly don't know where else to turn.
