Authorities are searching for a 19-year-old Arizona State University student who went missing Friday night, the Tempe Police Department said.
Jack Culolias was last seen leaving Cadillac Ranch in Tempe Marketplace around 11 p.m. on Nov. 30.
"Apparently Jack's mother found what she believes to be a shoe of Jack's down here by [Tempe Town Lake] and right now we are currently trying to find out more information on that," said Tempe Police Sgt. Mike Pooley.
Culolias was with other students from an ASU fraternity before he disappeared.
Culolias is described as standing six feet tall with black hair and brown eyes. He was last seen wearing a black t-shirt with "You'll shoot your eye out" printed on the front with a long-sleeved white shirt with gray or black horizontal stripes and blue jeans.
