The mom was preparing for the vigil when she and a woman driving a white 2016 Nissan Rogue got into a heated altercation over a memorial for the two girls that had been dismantled in front of a house on the block, cops said.

The woman was a relative of someone who lived at the home, according to police.

In video footage posted on Long Island News 12’s Web site, Rodriguez and a man can be seen confronting the driver.

That’s when the SUV driver accelerated and fatally struck Rodriguez, cops said. The network did not air that part of the footage.
