ORLANDO, Fla. (AP) - A retired prosecutor from the Casey Anthony murder trial has announced that he is running for the state attorney's office in central Florida.

In a video posted Sunday on the Orlando Sentinel's website, Jeff Ashton said he would challenge his former boss, Lawson Lamar, to be the Orange-Osceola State Attorney.

Lamar has served as state attorney since 1989.

Ashton says he would offer voters the choice between a prosecutor and a politician. He says he hopes the election won't focus on the Casey Anthony trial, which garnered national attention.

Ashton worked for the state attorney's office for 30 years. He retired as planned days after Anthony's trial ended in July. Jurors acquitted her in the killing of her daughter, Caylee.

Ashton has a news conference scheduled Tuesday morning.
