Guillen, 31 of Lufkin, Tomas Carreon and another friend had left Tuesday afternoon to help rescue stranded Harvey victims. On Wednesday, the radio station Y-100 Your Country Choice reported on their Facebook page that their boat had capsized after entering water with heavy currents.
Family members said Guillen;'s body was found in the same spot Carreon's was found Friday.
One of the men was able to hang on to a tree long enough to be rescued. He was recovered a mile from where the boat had capsized.
