"University police were notified shortly before 7 p.m. that a body was found in the water in the Wilmette Harbor. Maddula's wallet with his Northwestern ID card and his cell phone were found on the body. Wilmette police, who were on the scene, said there were no signs of foul play on the body," said Alan Cubbage, Northwestern University vice president for university relations.
The cause of death is under investigation and pending an autopsy Friday.
Cubbage said Maddula was a second year engineering student from New Hyde Park, New York. He said counselors are available for students.
A fisherman found the body floating near some boats, according to a witness.
Last Friday evening, Maddula was with friends at an off-campus party. He and others left around 12:30 a.m. Saturday morning, heading -- it is believed -- for another party when Maddula disappeared.
On Wednesday, divers searched the lake near Wilmette Harbor after they discovered Maddula's phone last pinged off a cell tower in that area just about an hour after he left the party.
Divers from the U.S. Coast Guard and local fire departments were involved in the water search. Crews using dogs also looked at boats docked in the harbor and the area nearby but they found nothing.
Maddula's parents flew to the Chicago area from New York earlier in the week to help in the search.
