Three men and one woman entered guilty pleas Monday in the 266th Judicial District Court on a variety of charges, ranging from possession and delivery of drugs to failure to comply with sex offender registration requirements.

Jonathan Mitchell Patterson, 27, pleaded guilty to two counts of delivery of marijuana, less than five pounds, a state jail felony. Patterson's charges were enhanced to third-degree felonies due to two prior convictions. He was sentenced to two 10-year prison sentences in the institutional division of the Texas Department of Criminal Justice. In exchange for his guilty plea, the sentences were set to run concurrently. He was also ordered to pay a $1,000 fine plus court, lab and attorney fees.

Following the proceeding, District Attorney Jason Cashon said the intent of the deal was an attempt to finally help Patterson understand the gravity of his crimes.

"It is against the law to deliver marijuana in the state of Texas. To keep committing the crime after already going to jail for the offense tells me Mr. Patterson has no regard for the law," Cashon said. "The only way I know to encourage him to develop that regard is for him to spend a significant period of time behind bars."

Thomas John Montgomery, 48, pleaded guilty to failure to register as a sex offender, a state jail felony.

Following a recommendation by Cashon, Montgomery was given the minimum sentence of 180 days in jail and was ordered to pay court costs.

According to the Texas Department of Public Safety's sex offender registry, Montgomery, a Dublin resident and employee of a Stephenville roofing company, served time in prison for indecency with a child when he was found guilty of exposing himself to a 13-year-old female in the 1990s. The registry also states that under the terms of his parole, Montgomery is required to register as a sex offender until May 2014.

Ana Bertha Aviles, 33, pleaded guilty to driving while intoxicated with a child passenger under 15, a state jail felony.

Aviles was sentenced to the maximum two years in jail, probated for five. Aviles' driver's license was suspended for one year and she was required to undergo a felony substance abuse treatment program, pay a $1,500 fine and perform 300 hours of community service.

Patricio Ramos Ortiz, 20, pleaded guilty to possession of a controlled substance in penalty group one, methamphetamine, less than one gram. Ortiz was placed on deferred adjudication probation and ordered to pay a $1,000 fine in addition to court and lab fees. He was also ordered to perform 300 hours of community service.
