FORT WORTH — A former Fort Worth teacher assistant has been sentenced to 10 years of probation for performing a sex act on a 15-year-old boy in the parking lot of a school in Richland Hills.In a plea bargain reached Friday, Moises Castellon, 25, of Fort Worth pleaded guilty to one charge of sexual assault of a child under 17 and was sentenced to probation with deferred adjudication.Castellon, who had been a special education assistant at Diamond Hill Elementary School, had been free since posting $100,000 bail after his arrest in May 2012.“He was eligible for probation and had a clean record,” Santiago Salinas of Fort Worth, Castellon’s attorney, said Monday. “This was a one-time situation.”Salinas said Castellon must also register as a sex offender for the rest of his life.Tarrant County Assistant District Attorney D.J. Estes said in an email Monday: “After taking into consideration all the circumstances in this case, including the youthfulness of the offender and the age of the victim, we felt this resolution included elements of treatment and punishment. He will be under intensive court supervision for the next 10 years and must complete a stringent caseload designed for sex offenders. If he doesn’t fulfill the conditions set out in the plea bargain, he could face the full range of punishment which is 20 years in prison. We wanted a guarantee for the strictest supervision for the longest period of time and this resolution meets those needs.”Officials said Castellon performed the sex act on a 15-year-old boy Dec. 31, 2011, after meeting him in an online chat room and arranging a meeting in the parking lot of Richland Middle School. The teen lived in Tarrant County.The man, who called himself “Junior,” performed oral sex on him in the man's black Toyota Corolla, according to an arrest warrant affidavit.The teen and the man arranged another meeting Jan. 17, 2012, the affidavit said. The teen had his mother drive him to the school after he convinced her that he needed to exercise, police said.The teen made an outcry in early April 2012 after going to Cook Children’s Northeast Hospital in Hurst.Authorities called Castellon on April 25, 2012, but he denied knowing the teen, going by the name “Junior” and owning a black Corolla, according to the affidavit.Police determined, however, that Castellon did drive a black Corolla.Days later, Castellon was placed on administrative leave from his job at Diamond Hill Elementary, school officials said then.Castellon joined the district in 2008, district records say.School officials and police have said that there was no indication that any child in his class or from the Fort Worth school was involved.
