CHARITON COUNTY, Mo. — A Mendon man whose wheelchair-bound passenger was lost when he drove into flood water has been arraigned in Chariton County.

Chariton County Courthouse

At the hearing Tuesday morning, the attorney for 45-year-old James W. Pleasant entered a not guilty plea and waived formal arraignment.

Pleasant is charged with first degree involuntary manslaughter in the May 31 disappearance of 33-year old Alicia Meyer.

Pleasant is accused of driving onto a barricaded road before his vehicle became submerged in flood water. He escaped the vehicle, but Meyer, who was disabled, was unable to exit the vehicle. Her body has not yet been recovered.

A setting or disposition hearing is scheduled for the afternoon of June 25. He remains behind bars at the Chariton County Jail.
