A white supremacist who admits killing three people outside two suburban Kansas City Jewish sites is set to appear in court for a hearing on whether he's mentally competent to stand trial.

Seventy-three-year-old Frazier Glenn Cross, of Aurora, Missouri, is charged with capital murder in the April 13 shooting deaths of 69-year-old Dr. William Lewis Corporon, 14-year-old Reat Griffin Underwood and 53-year-old Terri LaManno.

A Kansas judge last month ordered Cross to undergo a mental evaluation after his attorneys expressed concerns about his ability to help with his defense.

Cross told The Associated Press last week that one of his attorneys said he passed the evaluation "with flying colors." Results of the evaluation were to be revealed at a hearing Thursday morning at the Johnson County Courthouse in Olathe, Kansas.
