TEMPE, AZ - A group of Arizona State University students and volunteers have taken matters into their own hands in the search for missing 19-year-old Jack Culolias .
The students, along with two volunteer cadaver dogs and their owners are looking for clues to the Culolias' disappearance in the river basin by Tempe Marketplace.
The group is not getting paid to help with the search. One of the group members told ABC15, when they searched Monday afternoon, they weren't able to find anything.
She also said that if Jack is not found in a few days, that he is not likely in the lake because at this point in the decomposition he would surface very soon.
Another volunteer, Dayna Miller said "When all hope is given up that's when we come out and we continue searching so the families' feel like there's still hope that they're going to find their loved ones."
Jack's grandparents are also taking part in the search.
Jack was last seen being escorted by a bouncer off the grounds of Cadillac Ranch at Tempe Marketplace during a Sigma Alpha Epsilon fraternity-sponsored event at about 11 p.m. Friday, November 30 according to police.
