37-year-old Michelle Henson was last seen February 24, 2010, and was reported missing the next day. Two male acquaintances called the U. S. Coast Guard that day. The Coast Guard searched one day and did not resume searching. Law enforcement has talked with the two acquaintances but have no leads. Henson lived on board a houseboat offshore of Key West, in Cow Key Channel. Michelle had received her AA and was registered at the local college to continue her education. Michelle has not been seen or heard from since.
