LOUISVILLE, Ky. (WDRB) -- Divers are continuing to search of the Ohio River for a man who's believed to have drowned.

Around 8:45 p.m. Friday, crews called off the search due to darkness. Witnesses on the shoreline called 911 just after 12 p.m. Friday when they said two men were in the river and needed help. They were about 60 feet from the shore, where officials say it's about 10-20 feet deep.

Family members told WDRB News the missing man is 42-year-old Marcus Williams. He and the other man were fishing at the time of the accident.

"They were out fishing, and I believe they got a little too far out into a drop off or something," said Kevin Williams, Marcus' father. "And the current swept them under.

"He's a great son, father, brother ... He loves to fish, and he loves his two children."

More than 30 people responded and rescued one of the men around 12:40 p.m. He was given CPR and transported to Clark Memorial Hospital, where he is expected to survive.

"Both of them are very familiar with the area," said Indiana Conservation Officer Jim Schreck. "I'm being told they're both good swimmers.

Conservation officers were controlling the locks and currents near the Falls of The Ohio State Park so divers could continue to search Friday evening.

Dive teams scoured the area where Williams was last seen. Crews used special sonar equipment to assist them as family members waited for any kind of news.

"We are just comforting each other and sharing some of the fond memories and just praying to God to take care of us," Kevin William said. "Tell your children you love them every day, because you just don't know."

Officials said their main obstacle in the search is the terrain.

"If you've seen pictures of the Grand Canyon or even Red River Gorge, that's what is underneath the surface of the water here, except you can't see it," said Indiana Conservation Officer Jim Hash.

The search will continue Saturday morning.

"Our concern is finding closure and solace for the family," Schreck said.
