According to police, Samuel was drunk at the time of the rollover crash, which occurred on I-95 northbound in the infield adjacent to the University Avenue exit in Westwood near the Dedham line shortly before 4:20 a.m. Police who responded to the crash found the car submerged upside down in a flooded gully between the roadway and the ramp. Responding officers pulled both men from the car. Life-saving measures were performed but Samuel's passenger -- identified as 27-year-old Liam Fitzgerald, of West Roxbury -- died after he was taken to a local hospital, police said. One person died and another was injured when a car rolled over off of a highway in Dedham, Massachusetts.
