Omar Perez Garcia was arrested Jan. 6 on charges of false drug test, falsification device, according to Hidalgo County Jail records.

A criminal complaint obtained by ValleyCentral states that an officer was dispatched to the Hidalgo County Adult Probation Office in response to a false drug test in which Garcia met with a probation officer. The probation officer had requested Garcia perform a random drug test, the document indicated.

“[The probation officer] will testify that he Omar admitted to using a clear plastic bottle with liquid content to falsify the drug test,” the complaint stated.

According to the complaint, Garcia admitted to faking the drug test due to having smoked marijuana.
