A Virginia man is believed to have died after he jumped into the Potomac River to retrieve a fishing rod, police say.

The 31-year-old from Falls Church, Virginia, jumped off his 16-foot Stingray boat near Piscataway Park about 5 p.m., Maryland Natural Resources Police said.

The man tried to swim against the current to get back to the boat but could not, according to the U.S. Coast Guard.

The missing man is the owner of the boat and he was not wearing a life vest, police said.

Another man and a woman also were on the boat.

Rescue workers from Charles and Prince George's counties and the Coast Guard helped search for the man. Natural resources police said the search is now a recovery mission.

Authorities have suspended the search for the night and will continue searching Monday morning, police said.
