A Pasco man was sentenced to a month in jail for defrauding the court by giving a fake name when he pleaded guilty to drunken driving.

Juan Carlos Ramirez-Valdez, 32, pleaded guilty to one count of first-degree criminal impersonation. The sentence will be served while he is doing time for his Pasco Municipal Court case on the underlying offense.

According to court documents, Ramirez-Valdez was stopped April 2 and could not provide Pasco Officer Chad Pettijohn with a valid driver's license or identification. He told Pettijohn his name was Antonio Valdez Acevedo.

Pettijohn arrested him on suspicion of driving under the influence, reckless driving and no valid operator's license without identification, documents said.

Then on April 4 in Municipal Court, the city's prosecutor Bronson Brown offered Ramirez-Valdez a deal. Ramirez-Valdez talked with a defense attorney before pleading guilty to DUI, court documents said.

However, the court was unaware that Ramirez-Valdez was using an alias when he signed the paperwork with the Acevedo name, Brown said in documents.

If Ramirez-Valdez had used his correct name in that case, the mandatory minimum offered by the city would have increased because his criminal history includes DUI.

It is not clear when the fraud was discovered. In addition to his sentence, Ramirez-Valdez is in the Franklin County jail on a U.S. Immigration and Customs Enforcement hold.
