Suspected I-35 rock-thrower Patrick Johnson rejected a 30-year offer Wednesday in open court and told all parties he’d like a jury trial.

Prosecutor Leslie Booker told Johnson she is removing the offer from the table and will not present any counter offers. Johnson, who is already serving a 99-year sentence for sexual assault of a child, turned down a 40-year offer in the rock-throwing cases in November.

"The state is not going to go back and forth," Booker said.

Johnson, who is charged with four counts of aggravated assault with a deadly weapon, replied: "We’ll go to trial then."

A trial date will likely be set next month at Johnson’s Feb. 21 pretrial appearance. Johnson told Judge David Crain he is requesting a change of venue because of the publicity he’s received.

Austin police say Johnson was behind most of the 90-plus rock-throwing incidents on I-35 that began in 2014. No one was killed, but one victim suffered brain damage and another lost vision in his eye.

In September, a jury found Johnson guilty of sexually assaulting a 13-year-old boy he befriended at the mobile home community where they resided.

Johnson is charged with four felonies, and his attorney, Michael Watson, says they’ll be tried separately.
