This sounds awful. From New York 1:

A minivan jumped a sidewalk in Boerum Hill, Brooklyn Wednesday afternoon, killing one person and injuring another.

The minivan was traveling on Atlantic Avenue when it tried to make
a right turn and was rear-ended by an ambulette, causing it to jump the
sidewalk.

Witnesses say they were shocked at the crash.

"It’s terrible,” said one witness. “It was a big bang. I thought it was a bomb the way that car hit the building. Wow."

“The man who was killed — that’s a good friend. I know him for a
long, long time. He was a very nice, sweet man,” said an area resident.

The drivers of the two vehicles and the injured pedestrian were taken to Brooklyn hospital with minor injures.

No arrests have been made.
