Devastating house fire

My cousin has 2 kids of his own, 2 step kids, and a finace hes been raising. His house and everything he owned is now gone including their family dog. Luckily nobody was hurt but they have lost everything they have worked so hard for. There was a short in his breaker box and it blew up his house. And nothing is salvageable. Any help at all will definitely go to a good cause and be very much appreciated. Any questions please feel free to ask.
