Diego Enrique Angelini was 47 and an architect from Argentina when he was killed on October 31, 2017, during a reunion trip to New York City. He and classmates from the Polytechnic School of Rosario were cycling along the Hudson River Park bike path in Lower Manhattan to mark their 30th graduation anniversary when a rented pickup truck deliberately drove onto the path, striking cyclists and pedestrians.

The vehicle traveled roughly a mile before crashing into a school bus. Angelini and four friends were among eight people killed; several others were injured. The driver, Sayfullo Habibullaevic Saipov, 29 at the time, exited and was heard shouting Allahu Akbar before being shot in the abdomen by police and taken into custody. A note in the truck expressing allegiance to the Islamic State led authorities to treat the attack as terrorism and federal charges were filed against Saipov.

If anyone knew Diego, his travel companions, or was on the Hudson River Park path that day, please share what you remember.
