Marco Reyes-Sanchez, 21, of Reston is presumed drowned, officials said.
Reyes-Sanchez and another man jumped into the Potomac near Great Falls June 3. The other man emerged, but Reyes-Sanchez did not.
Montgomery County Fire-Rescue boats and personnel, as well as U.S. Park Police, were actively searching for the missing man from last Wednesday, when Reyes-Sanchez was reported missing, through Sunday, said MCFR spokesman Pete Piringer.
Piringer said a search of three to four days is typical in cases such as this one.
“We will continue to do passive searches,” he said. “And the U.S. Park Police will continue to notify boaters and kayakers. The [kayaking] community knows he is still missing. They are our eyes and ears on the river.”
