After many surgeries, state police said, Devlin succumbed to injuries suffered from the crash on Thursday.
On the day of the incident, Devlin was on patrol and stopped a car on Route 3 in Billerica, state police said. While outside his cruiser, he was struck by another car that drifted into the breakdown lane.
The driver of that car, a Haverhill man, was charged with negligent operation of a motor vehicle, marked lanes violation and failure to move over for an emergency vehicle. State police did not identify the driver in a statement issued Thursday evening.
