BALTIMORE >> An accident report shows the driver of the school bus that crashed in Baltimore this week, killing six people including himself, may have lost consciousness during an earlier crash two years ago.

According to the report released to The Associated Press on Friday, police in suburban Howard County said Glenn Chappell’s spouse told them at the time that he took medication for seizures.

The accident report from Feb. 9, 2014, says Chappell was driving in Ellicott City, Maryland, when he apparently “suffered a medical condition” and lost consciousness.

The report says the vehicle crossed a concrete median and oncoming traffic, eventually striking a guardrail. It continued on a sidewalk before coming to a rest after hitting some trees and shrubbery.

It says Chappell was taken to a hospital with no apparent injuries.
