Giant sinkhole

The article "sinkhole swallows florida man whole" is about a sink hole that comes during the night and swallows a man while he is in bed. In the article it says that the guy had heard a loud crash then heard his brother calling him and he went in to help him but it was too late. Also in the article it says that he was burried too deep almost 100feet and they were no longer going to look for him. Reading this article kind of makes me upset because I dont feel that they should have given up looking for him although he was probably dead. He was part of someones family and if they dont find him then that family may never have closure. I know if that were someone that was part of my family I would have never let them give up looking for him.
