The body of 31-year-old man who went missing while swimming off Rehoboth Beach, Delaware, on Sunday has been found following a massive search.

Richard A. Boateng, of Savage, Maryland, was last seen in the ocean surf off the beach area of Rehoboth Avenue around 5:45 p.m. Sunday, the Rehoboth Beach Police Department said.

The area is in the town of Rehoboth Beach, where President Biden has a vacation home.

Boateng's body was found Monday morning on North Shores beach, a small community just north of Rehoboth, Rehoboth Beach Fire Company Chief Chuck Snyder told Delaware Online.

A witness told WGMD that he saw somebody raise his hand out of the ocean and realized the swimmer needed help.

"Then I started shouting ‘Help! We need a lifeguard.’ We were shouting, shouting, shouting and finally when I turned to this side. I can’t see him. He just lifted his hand and he drowned," the witness said.

Officials had warned of rip currents throughout the holiday weekend.
