The driver who police say crashed into a Massachusetts State Police trooper's cruiser, killing him, is expected in court Thursday.
David Njuguna, 30, has pleaded not guilty to manslaughter and other charges.
Prosecutors say Njuguna smoked marijuana just before the March crash that killed state trooper Thomas Clardy.
Clardy had stopped a car for a traffic violation in Charlton on March 16 when his cruiser was hit by Njuguna's vehicle. Witnesses say Njuguna's car had swerved across all three travel lanes without slowing.
Clardy was later pronounced dead at a hospital. The 30-year-old Njuguna was hospitalized with serious injuries.
Njuguna's attorney says he denies being high on the drug.
