JEFFERSON CITY (AP) | A Cole County judge has ordered the release of a southeast Missouri man convicted 15 years ago in a college student’s murder.

Circuit Judge Richard Callahan ruled today that Joshua Kezer was wrongly convicted in the 1992 death of Angela Mischelle Lawless. She was found in her car on the Interstate 55 exit ramp near Benton, Mo., with the motor still running.

The judge’s 44-page ruling sharply criticizes the courtroom conduct of former state special prosecutor Kenny Hulshof.

Hulshof later served as a six-term Republican congressman from Columbia. He lost the 2008 governor’s race to Democrat Jay Nixon.
