Divers searched Blue Marsh Lake into the night Thursday after 23-year-old Samuel Burlacu disappeared as he struggled to swim across a stretch of water beneath a bridge.
Authorities say Burlacu had earlier jumped off the same cliffs where a teenager drowned last week. Fifteen-year-old Rood Sherac Nerjuste had moved to the area from Haiti in 2008.
The search was called off because of darkness. Rescuers resumed the search on Friday morning.
"You're not supposed to jump off the cliffs," said Shane Rose, of Robesonia, who was out enjoying Blue Marsh Lake on Thursday. "There's signs posted all over the place and ones on the bridge. You're not supposed to jump off the bridge or the cliffs."
Burlacu, of Reading, graduated from Albright College in May, said Dave Johnson, a spokesman for the school. He majored in religious studies.
Johnson said Burlacu's sister is also a student at Albright, and his mother is an employee of the college.
