SYCAMORE — Attorneys filed additional motions Tuesday in the case of the man accused of killing Northern Illinois University student Antinette "Toni" Keller.

During a hearing at the DeKalb County Courthouse, William "Billy" Curl, 36, of DeKalb, appeared in court via closed-circuit TV from the county jail.

He is charged with five counts of first-degree murder, one count of concealing a homicidal death, one count of arson and one count of criminal sexual assault in relation to Keller's October 2010 death. Curl was indicted in January 2011, and his trial is set to begin Dec. 3.
