Lamont Barkley, 55, got into a verbal dispute with a man and woman, believed to be boyfriend and girlfriend, on a BX19 bus at about 8:25 p.m. Sunday night.
The argument escalated and police say the man stabbed Barkley multiple times in the stomach at East 149th Street and Gerard Avenue. He died at the hospital.
Detectives first encountered 42-year-old Ebony Jackson on Sunday night at Lincoln Hospital, where she was being treated for injuries they believe she suffered in the scuffle.
Detectives believe Barkley first got into a dispute with Jackson at Glen Roy's bar at 145 East 149th Street, down the street from where he was killed. They believe when Barkley left the bar, Jackson called her boyfriend, who confronted then Barkley on the bus.
The boyfriend has not been apprehended.
Jackson remains at Lincoln Hospital, where she is being treated. She is being charged with murder and manslaughter.
Barkley's death is the eighth to happen in the transit system this year.
Last week, 38-year-old Charles Moore was getting off a northbound 4 train in the Bronx Thursday night when he was stabbed multiple times in the back and chest by a suspect who came up behind him in what police said they believe was an unprovoked attack.
Just hours before Moore was stabbed and killed, two other victims were stabbed in seemingly random attacks on the subway.
On Monday, riders said they now have more questions about where and if they are truly safe riding the city's transit, but many told Eyewitness News they don't have a choice.
"It's hard, and then you have to go to work through this in the morning and you go a couple of blocks down, it's becoming zombieville, it's just bad," one resident said.
