The 4-year-old girl who was struck and killed by a truck near Boston Children’s Museum has been identified by officials.

Gracie Gancheva died following the pedestrian crash in the Fort Point intersection on Sunday, Suffolk District Attorney Kevin Hayden announced on Wednesday.

“It’s difficult to adequately express the scope of tragedy in losing someone so young,” Hayden said in a statement.

“My staff and I extend our deepest condolences to Gracie Gancheva’s family, friends and loved ones,” the Suffolk DA added.

The incident occurred shortly after 5 p.m. Sunday at the intersection of Congress and Sleeper streets, near the Boston Children’s Museum.

Officers found the child lying on Sleeper Street. The girl was taken by ambulance to Massachusetts General Hospital, where she was pronounced dead.

The child was with family at the time. The driver of the Ford F-150 pickup truck that struck her remained on scene, and no charges, citations or arrests had been made. The Gancheva family lives in Denver, Colorado, according to published reports.

The incident remains under investigation by Boston Police accident reconstruction detectives.

The City of Boston has been targeting “major” safety upgrades at that Fort Point intersection.
