Rain forced the Ralls County Sheriff's Office to call off the search for a missing boater early Thursday night.
Terry Marshall, 60, of Hannibal went missing while mushroom hunting along the Salt River, according to Ralls County Sheriff Gerry Dinwiddie.
Family members and co-workers at the boat launch site off of Cincinnati Road near Center, Mo. said that Marshall worked at the Northeast Correctional Center in Bowling Green.
The Missouri Highway Patrol found Marshall's boat on a shore near Hunter Fisherman Access 70 Tuesday afternoon.
His truck was parked at a boat ramp.
Ralls County Sheriff Gerry Dinwiddie said three sonar boats and two K-9's were brought in to search the river Wednesday.
He said the Salt River, which connects to the Mark Twain Lake, was lowered five feet in total through a nearby dam to help with the search.
"Obviously we're looking for a good outcome here," MHP spokesman Sgt. Brent Bernhardt said. "When you're looking for a missing person, you're looking not only in the water, but along the bank, in the event that the subject is injured, maybe has gotten lost. So we're hoping for a good outcome."
