Police confirmed Tuesday that the man pulled from Tempe Town Lake on Friday was missing 24-year-old Willie Jigba.
The identification was made using latent fingerprint analysis, according to Sgt. Steve Carbajal.
Tempe police said Monday that preliminary autopsy findings were consistent with a drowning, but they are next waiting for toxicology results before they make an official determination.
Jigba, went missing Jan. 15 after leaving a party in the 900 block of East Weber Drive, about a half-mile from where dive team members from the Tempe Fire Department recovered the body.
During the autopsy, conducted Monday morning, no signs of trauma were found on the body and there were no signs of foul play, police said.
Cadaver dogs belonging to the Arizona Search Track and Rescue, a volunteer search team, picked up a scent last week along the water west of the Scottsdale Road bridge near the north side of the shore.
