Amid unusual security measures at the Buchanan County Courthouse, a teenager appeared before a judge on charges stemming from a quadruple-fatality accident on Riverside Road involving a stolen vehicle.

On Thursday morning, Prosecuting Attorney Dwight Scroggins filed two additional felony counts against Skylar Anthony Lucas-Cox.   He now faces two counts of involuntary manslaughter, class-c felonies, and one count of 2nd degree assault, a class-d felony.

A court affidavit lists two victims by initials for each of the manslaughter charges.

The defendant was kept in a small interview room nearby under guard of multiple law officers until the scheduled docket call was completed.

Lucas-Cox was then led into the courtroom.  About four dozen people were on hand in the courtroom of Associate Circuit Judge Rebecca Spencer, who explained the additional charges to the defendant.   Lucas-Cox waived his right to a preliminary hearing on all counts.

Judge Spencer certified the case for Circuit Court and scheduled arraignment June 1 before Circuit Judge Daniel Kellogg.

Lucas-Cox remains in custody without bail.

Four teenagers died in the crash April 14 near on Riverside Road near Cook Road.  Friends identified them as Karlo Ginn, Dayton Crockett, Dasean Darden and Javion Thompson.  A fifth victim remains hospitalized for critical injuries, but Scroggins says he is improving and is expected to survive.  Lucas-Cox was also seriously hurt in the crash as the driver of the other vehicle in the crash.

Court documents assert Lucas-Cox was driving recklessly in a stolen vehicle, and that after the crash he tested positive for cocaine, marijuana and benzodiazepines.
