New York City Police Commissioner Dermot Shea said the first attack happened on Friday morning when a 67-year-old man was stabbed by a masked assailant at the West 181st Street station in upper Manhattan. That victim is recovering in the hospital.
Late on Friday, a man was found stabbed to death on the A train at Far Rockaway-Mott Avenue station in Queens, police said. Two hours later, a 44-year-old woman was discovered unconscious with stab wounds on an A train at the 207th Street station in Manhattan. She was pronounced dead at a hospital.
In a fourth incident early Saturday, a 43-year-old man was stabbed back at the West 181st Street station. He underwent surgery and is in a stable condition, police said.Detectives said the attacks, all on the A train or at stations served by it, were unprovoked and that they are investigating whether they were all committed by the same person.
New York City police deployed hundreds of officers to the subway system on Saturday in an attempt to find the perpetrator of a string of stabbing attacks that left two people dead over 14 hours. Shea said the New York Police Department was immediately deploying 500 additional officers to the city's transit system in response.
"Bottom line that the public should know is this: They can expect to see a very large footprint of uniformed officers," Shea told reporters at a news conference. "Whether they go onto a train, whether they go onto a platform, and they'll be there as long as needed to make sure people feel safe."
“The Detective Bureau is looking into the possibility that all four could have been committed by one individual,” Transit Chief Kathleen O’Reilly told reporters at a press briefing at NYPD headquarters in lower Manhattan, according to the New York Post.
“We will work tirelessly to bring the individual or individuals to justice.”
