Excerpt:
Umer Ahmad, a 43-year-old Muslim-American physician from New Jersey, was in his Trenton office when he heard that a rented pickup truck had deliberately driven down a bike path in Lower Manhattan, killing eight people and injuring about a dozen more.
"My initial reaction was, obviously, concern and shock over what happened," Ahmad told NBC News. "And then, basically, I was wondering if it was a Muslim who did it."
The suspect was identified as an Uzbek immigrant named Sayfullo Habibullaevic Saipov, 29, who entered the United States in 2010, law enforcement officials said.
