MARION, Ind. (AP) — A truck driver accused of falling asleep at the wheel of his rig and causing a highway crash that killed five people, one of whom was misidentified for weeks, was arraigned Thursday on five counts of reckless homicide.

A judge entered a preliminary plea of not guilty on behalf of Robert T. Spencer, who was taken to Indiana on Wednesday after waiving extradition in Michigan.

Spencer's semitrailer crossed an I-69 median and collided with a Taylor University van on April 26, killing four Taylor students and one faculty member. The case drew national attention five weeks later, when authorities discovered they had mixed up the identifications of two students, one killed in the crash and the other severely injured.
