NYPD officers are searching for a man who allegedly pushed another man to his death in front of a subway train in Manhattan on Monday afternoon.
Ki-Suck Han, 58, of Elmhurst, Queens, was shoved in front of a southbound R train at the 49th Street station at around 12:30 p.m., according to NBC New York.
He was later pronounced dead at St. Luke's Hospital.
Witnesses said the suspect (pictured above) was mumbling to himself before getting into an argument with Han on the platform and shoving him onto the tracks.
After falling, Han tried to climb back up on the platform but was struck by the train before he could make it to safety and never recovered from the impact.
One witness videotaped part of the verbal altercation (above) and turned the tape over to police, which released it in an effort to identify the suspect.
It's unclear what triggered the dispute, but the suspect was clearly heated about something and exchanged pointed words with the late Ki-Suck Han.
The man was last seen wearing a dark jacket, a gray T-shirt and a cap. He is pictured below. If you have any information, please contact NYC police.
