EVANSTON (AP) — Police are fanning across Evanston seeking information in the death of a Northwestern University student whose body was found in a harbor near the school's suburban Chicago campus.

Harsha Maddula of New Hyde Park, N.Y. was last seen leaving a party where authorities say he was observed drinking alcohol. He left shortly after midnight Sept. 22, and his body was recovered Sept. 27 in Wilmette Harbor, which is located 1 1/2 miles from the party site.

Authorities are trying to determine Maddula's actions between shortly before he left the party and the last signal from his cellphone about 2 1/2 hours later.
