A former associate athletic director at the University of Texas Friday was under investigation after $50,000 to $60,000 were discovered missing.

Neither University of Texas police nor athletic officials would comment on camera Friday. They would only say Doug Wilson was no longer on staff.

Police are investigating what happened to money he was responsible for.

According to a search warrant, police believe Wilson "has possession of and is concealing... checks, cashier's checks, money orders, receipts, US currency and other records related to the Texas Relays."

Texas Relays is an annual track and field event held at the University of Texas that draws thousands from across the state. It's an event that Wilson had directed since 1992.

But since 2001, tens of thousands of dollars associated with Texas Relays has gone unaccounted for.

While executing the search warrant, UT police recovered dozens of old checks -- "entry fees" for Texas Relays paid by school districts across the state. The checks were found in Wilson's office at Darrell K. Royal Memorial Stadium -- they hadn't been cashed.

“A recent audit revealed that from 2001 to present, approximately $50,000 to $60,000 has not been deposited into the appropriate UT account,” according to the affidavit. Police said the majority of the money missing is cash.

"My initial reaction would be shock and kind of disappointment in the whole institution," said UT student Alison Smiley.

Police are still investigating why the checks recovered were never deposited. They said a lot of the money is still unaccounted for.

Wilson has not been charged with a crime.

Police said this investigation will be a lengthy process with all of the internal audits.

UT officials would not KVUE News if Wilson was fired or if he chose to resign or retire.
