SYCAMORE – Attorneys have a month to file additional motions in the case of the man charged with killing Northern Illinois University student Antinette “Toni” Keller.

William “Billy” Curl, 36, appeared in court Thursday via closed-circuit TV from the DeKalb County Jail. Prosecutors received supporting documentation for a psychological evaluation of Curl, which his attorneys turned over two weeks ago.

Curl’s trial is scheduled to begin Dec. 3, so Oct. 23 was established as the cut-off date for pretrial motions to be filed by either his attorneys or the state.
