SYCAMORE – William “Billy” Curl still is scheduled to stand trial next month for allegedly killing Northern Illinois University freshman Antinette “Toni” Keller in October 2010.

A judge denied his motion Thursday to dismiss the murder charges. An attorney for Curl, 36, of DeKalb, argued that he could not adequately prepare his defense because the indictment did not specify what acts caused Keller’s death.

In addition to the murder charges, Curl is accused of concealing a homicidal death, arson and criminal sexual assault in connection with Keller’s death. Keller was last seen Oct. 14, 2010, when she told friends she was going for a walk in Prairie Park. Her burned body was found in the park two days later.
