The 77-year-old victim of a Feb. 28 hit-and-run has died, Middlesex County District Attorney Marian Ryan and Cambridge Police Commissioner Robert Haas confirmed Tuesday.

Dorothy Steele was on Columbia Street in her wheelchair when she was struck at about 4:40 a.m. in her wheelchair on the southbound lane of Columbia Street near Lincoln Street. She sustained serious injuries and was taken to Massachusetts General Hospital, where she lingered in critical condition and after more than two weeks succumbed to her injuries.

Steele reportedly lived alone in a senior housing complex but was out frequently, despite the wheelchair and cold weather.

The driver of the vehicle that struck her has been identified as Henry Park, 62, of Somerville, police said. They believed the driver had fled northbound after the crash, heading toward Somerville via Webster Avenue and Prospect Street, leading police to start a search for a vehicle with damage to its front bumper, headlight and possibly hood. Police believed the driver to be the only person in the car at the time.

Police found the suspect car on the afternoon of March 3.

With Steele’s death, a charge for Park has been filed: leaving the scene of a personal injury causing death. Previously he had been issued a citation for leaving the scene of a crash causing personal injury.

An arraignment date has yet to be scheduled.
