Absent 'Thank You' Spurred Fatal Park Slope Stabbing: Report

PARK SLOPE, BROOKLYN —An argument over absent thanks claimed the life of the man stabbed to death outside a Park Slope smoke shop earlier this week, according to a new report.

The fight on Fourth Avenue and President Street Tuesday night began when a man who held open the door for a fellow customer didn't receive a thank you in return, the Daily News reports.

The 37-year-old victim said, “you didn’t even say thank you,” to which the soon-to-be stabber replied, "I didn't ask you to hold it," reports the Daily News.

Video obtained by the news outlet shows the two men pushing and shoving each other against a large display case then taking the fight outside where another camera follows the action.

The 37-year-old — whose name is in the Daily News report but was unconfirmed by police — tries to stop his opponent from riding away by first knocking over his e-bike then slapping him in the face, the video shows.

The suspect's arm thrusts towards his abdomen before riding off southbound on Fourth Avenue. The victim turns toward the camera and his white shirt is stained blood red.

Police had no updates on the case as of Thursday morning, saying that the investigation is still ongoing.
