(KNZA)--A St. Joseph teen charged in connection with a two-vehicle collision in April  that claimed the lives of four other teens appeared in a Buchanan County courtroom Thursday morning.

17-year-old Skylar Lucas-Cox waived formal arraignment and entered a plea of not guilty to two counts of involuntary manslaughter and one count of 2nd degree assault.

A trial date is expected to be set during a June 22nd hearing.

Authorities say Lucas-Cox was driving a stolen pickup April 14th near the intersection of Riverside and Cook Roads in the northeast part of St. Joseph when he lost control of the vehicle and crossed into oncoming traffic, striking another vehicle head-on.

Four teens in the pickup, ranging in age from 15 to 17, died as a result of the crash.  Three others, including Lucas-Cox, were seriously injured.

Lucas-Cox continues to be held in the Buchanan County Jail without bond.
