A former Del Valle school bus driver was sentenced to four months in prison Wednesday for soliciting a minor online, the Texas Attorney General's Office said.

Michael Richard Schweitzer, 56, of Cedar Creek, was charged with online solicitation of a minor after investigators with the attorney general's Cyber Crimes Unit say he sent explicit materials to someone he thought was a 13-year-old girl. It was actually an undercover investigator.

Schweitzer pleaded guilty, and once his sentence is complete, he will have to register as a sex offender for 10 years.

“Few things are more frightening to parents than a sex predator driving their children to school each morning,” Attorney General Greg Abbott said in a news release. “The Cyber Crimes Unit will continue working tirelessly to protect Texas children.”

Schweitzer was arrested in October 2007.
