Human remains have been located, but Kristy, an experienced scuba diver, is still considered missing. An investigation into what caused the fire is ongoing.
At a Tuesday morning press conference, crews announced they're now executing a search and rescue mission to locate the bodies of the deceased.
"My parents called me (Monday) morning and said 'Brett, we don't have very good news,'" he said.
The man tells ABC13 he was supposed to have been aboard the boat, as well, explaining his sister had an open spot and extended an invitation for him to join, but he was unable.
"I was shocked when they told me my sister was on the boat," Brett said.
