Officials with Cleveland Metroparks provided no additional details at a briefing about the deaths of 40-year-old Carnell sledge, of North Olmsted, and 33-year-old Katherine Brown, of Fairview Park.

Their bodies were found Tuesday by kayakers at the Rocky River Reservation, which is near Cleveland Hopkins International Airport.

Authorities have not said how the man and woman knew each other.

Authorities said this is an isolated incident, and the parks are safe.
