Records: Halifax Teen Smoked Marijuana Before Crashing Into School Bus

HALIFAX (CBS) – A Halifax teenager, already in trouble with police for a crash one year ago, may be part of a larger drug investigation.

Monica Knight was driving a BMW last year, driving three of her friends to Silver Lake High School, when she crashed into a bus. Her friends were seriously injured, and one, Eva Lipton, is still on life support.

Court documents reveal that Knight was smoking marijuana just prior to the accident.

She has been held in jail for the past week, after she tested positive for marijuana, a violation of her probation order. She was released Friday, after being fitted with a GPS bracelet.

WBZ has learned that Knight may be part of a larger investigation, into marijuana distribution in the Halifax area.
