Investigators say they've found prescription painkillers in the pickup truck that plowed through a formation of motorcycles, killing three riders.
The Texas Department of Public Safety reports a search of the truck after the Saturday crash also turned up a leafy substance. A search warrant affidavit reviewed by the Corsicana Daily Sun shows DPS Trooper Chris Williamson detected "a strong odor of marijuana" in the truck cab.
