BANGOR, Maine (NEWS CENTER) - Kyle Dube was arraigned today at the Penobscot Judicial Center where he plead not guilty to kidnapping and murdering Nichole Cable.

Dube's lawyer requested a competency hearing to determine abnormal condition of mind. Dube will continue to be held without bail.

The State Medical Examiner's office has said the cause of death for 15- year old Nichole Cable was from "asphyxia due to compression of the neck."

The Glenburn teen disappeared from her home on May 12th. Her body was found eight days later.
