Jonathan Jay Franklin, 25, was last seen May 31, 2013, during a float trip on the Meramec River near Times Beach in Eureka, Missouri. The group entered the water in the Pacific Palisades area; the spot where he vanished is described as the confluence with the Big River about two miles upstream from the Route 66 State Park Boat Ramp. He was wearing green and white swim trunks and water shoes, and is described as 5 feet 11 inches, 175–200 pounds, with brown hair and brown eyes and a tattoo of praying hands and John 3:16 on his left shoulder.

Severe storms moved in soon after he was last seen, causing the river to rise and creating dangerous currents that hampered search-and-rescue operations. Family, friends and community volunteers searched daily by air, boat and on foot from Eureka down to Arnold, and his family from Peoria, Illinois, traveled back on weekends to continue the search and distribute flyers. The Missouri State Highway Patrol is listed as the investigating agency. Jonathan remains classified as a missing person.

Did anyone float the Meramec around late May 2013 or see a group near the Times Beach area that day?
