Two kayakers pulled a man’s body from the Potomac River Wednesday just a few hundred yards from the Key Bridge in Georgetown.

It was the fourth body found in a District waterway this month, though the Metropolitan Police Department told the Washington Post there did not seem to be a connection between the cases.

At least one death may have been a suicide and another an accident, the Post reported. Relatives of a person found in the Anacostia River suspect foul play. Detectives have yet to receive the results of autopsies.

D.C. officials told the Post that clusters of such deaths have occurred in the past, such as when three bodies were found in the Anacostia River between July and October 2011.

Student rowers from Wakefield High School, a school in Arlington County, discovered a body in the Anacostia River on April 1, who was later identified as 36-year-old Arlester Jay. Relatives told the Post that they do not believe the death of the Iraqi war veteran – who went missing from Prince George’s County in March – was an accident.

A fisherman found the body of Robert Groshan, 36, in the Potomac River on April 6, the Post reported. Police suspect Groshan, a D.C. resident, committed suicide.

Kumar Potharaju, 35, disappeared Easter Sunday while visiting the District from Chicago, and his body was found in the Tidal Basin at the peak of the cherry blossom season April 11. MPD told the Post that Potharaju might have fallen into the 10-foot deep water.
