BALTIMORE (AP) - Investigators in Baltimore are focusing on speed as they delve into the collision between a school bus and a commuter bus that killed both drivers and four mass-transit riders.
City police spokesman T.J. Smith said Wednesday that both vehicles were moving "at a pretty good rate of speed" when the school bus crossed the center line and smashed into the Maryland Transit Administration bus early Tuesday morning. But he says investigators haven't determined how fast they were going.
The National Transportation Safety Board tweeted a photo of its investigators doing a three-dimensional scan of the wrecked school bus.
One thing that won't come quickly is an autopsy report on 67-year-old school bus driver Glenn Chappell. Smith says it could be weeks before investigators know if he suffered a medical emergency.
