SOMERVILLE — A 55-year-old Norwood man has been arrested in connection with the hit-and-run accident that killed a local woman on Powder House Boulevard last Friday, authorities said.
Edward Clark of Norwood is facing a charge of leaving the scene of the accident, which killed Allison Donovan, Middlesex District Attorney Marian Ryan announced at a news conference late Thursday afternoon.
Clark is scheduled to be arraigned Friday in Somerville District Court. The investigation is ongoing, and Ryan said additional charges are likely.
Donovan was struck and killed last Friday evening on Powder House Boulevard near the intersection with Hardan Road in Somerville. A woman walking with Donovan also was hit but was later released from the hospital, officials said.
Ryan said the preliminary investigation suggested that Clark was driving a black Ford F-150 at about 7:15 p.m. eastbound on the boulevard when he allegedly struck the two women in a crosswalk at the intersection. Authorities allege he then fled the scene.
Investigators were able to secure images from surveillance cameras in the neighborhood during the immediate aftermath of the crash. On Thursday, a Tufts University police officer spotted a truck with front-end damage that was thought to be the suspect’s truck on University Avenue, authorities said.
The officer notified Somerville police, and investigators found Clark, the registered owner of the truck, and placed him under arrest.
“It was basically just good old-fashioned, boots-on-the-ground police work that allowed us to give closure to the family,” said Somerville Captain Christopher Ward at the news conference.
Donovan, 40, lived near the crash site. A veteran educator, she worked for Watertown Public Schools as a K-8 literacy and Title 1 coordinator. She was formerly the principal at the Lincoln Elementary School in Melrose. Her funeral was held on Thursday.
Somerville Mayor Joseph Curtatone, speaking at the news conference, offered condolences to Donovan’s family and said the community was grieving her death. He described Donovan as “the most sincere, loving, compassionate person.”
“It has been a big loss for all of us,” said Curtatone.
A vigil is scheduled for Friday evening to remember Donovan and support her injured friend.
On Thursday night, a sidewalk memorial was still at the intersection, across the street from the West Somerville Neighborhood School. Flowers and candles were grouped around a pole on the sidewalk. Affixed to the pole was a sign that read “Slow down for Allison.”
Sarah Nordeen, a 27-year-old graduate student at the Massachusetts Institute of Technology, has lived at the intersection for three years. She said sometimes drivers on that stretch of road don’t stop for pedestrians despite the ample signage, stanchions in the road, and yellow lights that flash when someone presses a button before crossing the road.
“I’ve almost been hit at that crosswalk as well,” she said.
She welcomed the news of the arrest.
“That’s the thing that bothers me the most — he left,” she said.Martin Finucane of the Globe staff contributed. Danny McDonald can be reached at email@example.com. Follow him on Twitter @danny__mcdonald.
