The Boston Police Department is asking for anyone who witnessed a fatal crash that killed a 3-year-old to come forward.
Police are seeking to obtain videos or photos that may have captured the crash or the aftermath. A van involved in a crash jumped onto the sidewalk in a Boston neighborhood, struck and killed a 3-year-old boy in a stroller and injured his 4-year-old sister.
The woman pushing the stroller was unhurt.
Police say the van and a car collided on a South Boston street at about 3:15 p.m. Wednesday, and the van jumped the curb.
The street, which would have normally been lined with parked cars, was empty for a scheduled street cleaning.
Police Commissioner William Evans called the situation a "nightmare," and said the young girl is expected to survive. It was unclear whether the woman pushing the stroller was the children's mother or a caretaker.
Both drivers stayed at the scene, and no charges were announced.
No names have been released.
Anyone who witnessed the crash and anyone who has photos or videos is urged to contact Sergeant Detective Thomas Barrett at firstname.lastname@example.org.
