A motion filed in a municipal court Thursday revealed that the money missing from the Pflugerville Police Department evidence room is related to an alleged gambling house seizure that occurred in 2010, the Austin-American Statesman reports.

According to the Statesman, six years ago Pflugerville police obtained a warrant to search a home in the 15603 block of Connie street after there were reports someone was conducting an illegal gambling operation there. Pflugerville police obtained more than $500 from the house with the assistance of the Texas Comptroller's Office.

According to the report, the City of Pflugerville put a notice in the Pflugerville Pflag and Round Rock Leader newspapers for the rightful owner to come and pick up the money before Dec. 28, 2016. However, when a person went into the police department to claim the funds, officials discovered the money was missing.

According to City of Pflugerville spokesperson Terri Toledo, the process for claiming money from the police department is supposed to happen months after the investigation. Yet , in this case, a notice wasn't released until six years later. The original investigation into the alleged gambling case was also closed on Nov. 16, 2011.

The Texas Rangers began their investigation into the incident several months ago, but they have yet to arrest anyone. Their report on the investigation is set to come out in the next few weeks.
