NEW YORK (CBSNewYork) -- A man was killed Thursday evening after being shoved in front of an oncoming Subway train, police said.
Investigators continued to look for a female suspect, who is believed to have pushed the victim as a Queens-bound "7" train sped into the 40th Street-Lowery Street station around 8 p.m., 1010 WINS' Eileen Lehpamer reported.
Citing several witnesses, police told reporters that the suspect was seen mumbling and talking to herself before sitting down on a wooden bench by herself.
Authorities said the woman then waited until the last possible second before approaching the victim from behind and pushing him onto the elevated tracks.
"From what I understand...it would appear the train was very close when he was pushed into its path," Deputy NYPD Commissioner Paul Browne said.
"Oh my God. That ... I've never heard of that. That is really ... a woman pushed a man. ... Oh my God. That is really crazy," Woodside resident Shiek Hossain told CBS 2's Derricke Dennis.
"I think that's horrible -- so many crazy people running the streets," Beverly Gonzalez added.
Witnesses said the victim didn't notice the suspect, who police described as a heavyset Hispanic woman in her 20s, approximately 5-foot-5, with brown or blonde hair.
The unidentified woman was said to be wearing a blue, white and gray ski jacket and Nike sneakers. She fled down stairs following the push, police said.
Police said surveillance video from a pizzeria across the street from the station may have captured the suspect running away. Investigators were taking a close look at the footage late Thursday night.
"I hope they can find something," restaurant owner Giovanni Briones said.
The Metropolitan Transportation Authority said 7 train service was being disrupted as a result of the incident.
The incident marked the second deadly subway push this month. Back on Dec. 3, police said Ki Suck Han was pushed to his death by 30-year-old Naeem Davis.
"It's very sad. It seems people are doing this over and over. I don't know why," Hossain said.
