Human remains found by a kayaker in Florida have been identified through DNA as those of Rose Marie Gayhart, a 23-year-old woman who disappeared in 1985. The identification closes a decades-long missing-person mystery for her family, but police are now treating the case as an unresolved homicide investigation and seeking information about who killed her.

Gayhart was reported missing by her parents in March 1985, when they were living in Dansville, New York. Before she vanished, she was known to be living and working in the Cape Coral and North Fort Myers area of Florida; investigators have been searching for answers in her case for more than 40 years.
