AUBURN, Ala. — A psychological evaluation has found that the suspect in the slaying of an Auburn University freshman from Marietta has been faking hallucinations in jail and is fit to stand trial on a robbery charge, The Birmingham News has reported.

Courtney Lockhart faces several robbery charges and has pleaded not guilty to the March 4 slaying of 18-year-old Lauren Burk.

A Russell County Circuit Court judge ordered the evaluation in April to determine whether Lockhart was competent to stand trial for an armed robbery in a Wal-Mart parking lot.

Lee County Circuit Court Judge Jacob Walker ordered a separate evaluation last month to determine if Lockhart is competent to stand trial for both the robbery and Burk's murder.

The court ordered that the results of that evaluation be sealed and proceedings in the case have been postponed pending the outcome of the second evaluation.
