ROUND ROCK, Texas (KXAN) — Police arrested a man living in the country illegally after they say they found a fake driver’s license with a dead man’s identification number on it.

Round Rock police booked Omar Santillan Yanez, 39, into the Williamson County jail on Jan. 12 after a traffic stop on University Boulevard near College Park Drive.

According to an affidavit, police pulled over Yanez initially for a broken brake light. When the officer asked to see his driver’s license, police said Yanez first told them he didn’t have it on him, then he reportedly said he didn’t have one at all.

The affidavit states, “When asked why he stated that[,] he doesn’t have ‘papers’ and stated that he was in the country illegally.”

Police said a Mexican voter registration card helped them identify Yanez. According to the affidavit, a criminal history check by dispatch revealed several charges for driving while intoxicated, driving without a license, drug possession, tampering/fabricating evidence and immigration charges.

“It should also be noted that the Defendant had multiple active suspensions of his driving privileges,” the affidavit states.

Police said Yanez gave them permission to search his SUV, where they said they found a fake Texas identification card. “Based on my training and experience,” the officer wrote in the affidavit, “I knew the card to be a fake due to the layout and coloring.”

Police reported that the ID had Yanez’s picture on it, but it listed his name as “Jose Eli Ventura” and had a different birth date.

When police ran the ID number listed on the fake card, they said the number had belonged to another Texas man who died. An online search for that man’s obituary revealed that he died in November 2017.

The officer wrote in the affidavit, “[Yanez] told me that he used the ID to get a job.”

Police said Yanez later told them that he bought the ID from another man for about $70 in 2018. The affidavit states Yanez reportedly told police that he “provided the male with a name, photo and a date of birth for the new ID card.”

Police confirmed Wednesday that they’re going to investigate who made the ID, but it’s too early to share any information about its origin.

Police said the name used on the card, Jose Eli Ventura, matched a Social Security card found in Yanez’s wallet. The affidavit said, “The Defendant states he ‘found’ the card during a flood. He also admitted that he used this social security card to help create his fictitious ID.”

Yanez was booked into the Williamson Count Jail on one felony count of fraudulent use/possession of identifying information as well as two misdemeanor counts of driving with license invalid with a previous conviction or suspension without final resolution and driver license/ID false.
