Authorities say a woman who died at Patoka Reservoir over the weekend succumbed to a heart problem.

Conservation Officer Jeffrey Milner says 55-year-old Patti Hoskins-Owens died of an “acute heart event.”

An autopsy was performed Monday.

Officers say Hoskins-Owens had been in the water on a raft Sunday afternoon when she cried for help getting back to a boat.

Once on the boat, she became unresponsive.

The incident occurred in the Sycamore Creek area of the reservoir.
