Hartford, Ill. (KSDK) -- Search and rescue officials now say the two men, missing after a fishing boat capsized on the Mississippi River Saturday, are friends who are ages 49 and 60.

Hartford Fire Chief David Owens II said Sunday the men are from the Bellefontaine Neighbors/north St. Louis area. One of them is the stepfather of the 10-year-old boy found floating down the river about 1:30 Saturday. He was rescued by a passing barge crew.

Owens says the families of the missing men have declined to have their names released.

Several area departments helped search the banks of the river Sunday, and the river itself.

Chief Owens said, "The Illinois Dept of Conservation has brought 3 boats down with sonar. So currently we have 3 boats on the river with sonar sweeping the shoreline."

Owens says they believe the boy was in the water for 10-15 minutes Saturday. Officials believe the three got on the river at the public launch site on the Missouri side by the Alton lock and dam.

Owens says the boy was released to his mother yesterday. Owens said the child was in Hartford Saturday night, and is said to be in good condition.
