The Douglas County Coroner's Office confirmed the body recovered from the Missouri River Wednesday is that of 23 year old Aung Thu.   The cause of death has been ruled a drowning.

Omaha police rushed to NP Dodge Park Sunday evening to help Omaha Fire Department rescue crews with a river search.  They were told a young male had been swimming in the river with family.  Witnesses say he swam toward the center of the river and disappeared.  When he didn't return to shore witnesses called 911. 

The Omaha Fire Department rescue boat checked the water and others walked the river bank looking for the man.  Officials with the U-S Coast Guard were also contacted about the missing person.
