A red shoe that appears to belong to 19-year-old ASU freshman Jack Culolias remains the only sign of the missing fraternity pledge since he was last seen Friday night.
Tempe police Sergeant Michael Pooley said yesterday that the shoe is the strongest lead police have, although he did say police are investigating other factors in the disappearance that aren't related to the search.
He wouldn't comment any further on what the other parts of the investigation are, although he did confirm that no one had been arrested or detained.
Culolias was kicked out of Cadillac Ranch in Tempe Marketplace around 11 p.m. Friday -- where he used a fake ID to get in -- during an event with the Sigma Alpha Epsilon fraternity, in which Culolias is a pledge.
Although there have been reports that police are investigating possible hazing of Culolias, that doesn't appear to be the case, although it's relevant.
Culolias' mother -- a California resident, who ended up filing the missing-person report with ASU police on Sunday -- told police that her son had been fearful about the prospect of being hazed in the coming week, as a fraternity pledge.
That apparently led police to interviewing Sigma Alpha Epsilon members, who seem to be the last people who saw Culolias, during their event at the bar/restaurant in Tempe Marketplace. That discovery led to Tempe police taking over the investigation.
Police are doing a DNA test on the red shoe -- which Culolias' mother actually found when she started searching near Tempe Marketplace with her son -- to find out if it's really his.
Other than that, there aren't very strong leads as to what happened to Culolias.
Pooley said that Cadillac Ranch does have surveillance footage from the night, but it's not exactly high-quality, and there are hundreds of people on the tape. Investigators weren't able to identify him in the footage.
Pooley declined getting into the details on what could happen to Cadillac Ranch, as Culolias appears to have been served alcohol using a fake identification.
"[I'm] not going to get into that right now," he said, adding that police are focused on the search at the moment.
Pooley said police were using a robot with sonar to search the edge of Tempe Town Lake, which extends to a riverbed of the Salt River, and a Maricopa County Sheriff's Office helicopter -- which we had seen in the area that morning -- was still flying around. K-9 units specifically trained to find humans were brought out as well, but there hasn't been any sign of him.
