Pat Johnson heads to court to face sexual assault charges against a child. He's also the main suspect in several case of rock throwing on I-35.
Three years ago Johnson was indicted for sexual assault of a child and his case finally goes to trial after jury selection wrapped up on September 19.
60-year-old Johnson pleaded not guilty to two counts of sexual assault of a child, one count of indecency with a child by contact and one count of indecency with a child by exposure.
The victim told police he met Johnson when he was 12 and the two would hang out in his trailer. According to court documents, the victim said Johnson began assaulting him when he was 13. He says it lasted for two years and Johnson would give him drugs and money.
A grand jury indicted Johnson in 2013 and he was out on bail when the rock throwing cases started.
Between 2014 and this summer, there were nearly 100 cases of rocks being thrown off I-35.
Johnson is the Austin Police Department's main suspect in those rock throwing cases. He was arrested in June and is charged in seven of the cases so far.
If Johnson is convicted on these sex assault crimes he could get life in prison.
