OKLAHOMA CITY (AP) - Federal transportation officials say a small pipe containing synthetic marijuana residue was found in a semitrailer after it crashed into a Texas college softball team's bus in Oklahoma last year, killing four players.
National Transportation Safety Board officials discussed the findings of their investigation Tuesday during a hearing in Washington about the crash involving the North Central Texas College team.
They allege that the truck driver, Russell Wayne Staley, of Saginaw, Texas, had a history of using the drug and didn't try to avoid hitting the bus in the opposite lane. But NTSB medical officer Dr. Nick Webster says a blood test couldn't confirm the presence of the drug in Staley's system.
Staley is charged with four counts of first-degree manslaughter. His lawyer didn't immediately respond to a call.
