“That’s three down and one to go. We hope this sends a message that public corruption is not going to be tolerated in Tarrant County and we respect the jury’s verdict,” said Assistant Tarrant County District Attorney, Matt Smid. “It’s a lot of hard work… a lot of exhibits to go through and we appreciate their efforts.”

Johnson, who sat quietly as the judge read the jury’s decision,  was sentenced to five years probation and must pay Tarrant County $8,062.59.

He was found not guilty in six other counts of tampering with a government record.

Johnson was indicted after a CBS 11 I-Team investigation found him providing private security for Walmart while he was supposed to be on duty for the county.

Defense attorneys argued Johnson was following the orders of a chief deputy who pleaded guilty last year to the same scheme.
