Ross Brandon Sudbrook, 23, of Old Riverside Drive in Baltimore, has been charged with assault and reckless endangerment as a result of the stabbing.
Investigators said the accident and assault stemmed from an altercation between the driver of the Explorer and a 23-year-old male passenger in the other car. Police said that the driver and passenger in the Explorer exchanged seats on at least one occasion at another intersection along Route 3 and the delay led to an exchange of words between the occupants of the two vehicles. At Route 3 and Riedel Road, the 44-year-old man, driving the Explorer, got out of the car and confronted Sudbrook, the PT Cruiser passenger. Sudbrook then stabbed the man in the upper body and the cruiser fled north on the highway, police said.
The Explorer driver pursued the fleeing car and forced it off the highway and the vehicles collided. A fight ensued. Both men were taken to University of Maryland Shock Trauma. The 22-year-old woman driving the PT Cruiser and two passengers in the Explorer were taken to area hospitals with injuries that were not life-threatening, police said. The parties involved did not know each other, police said.
Sudbrook also faces charges for carrying a dangerous weapon. The incident remains under investigation and could result in charges for the other driver, police said.
