A dispute over noise in a Brooklyn apartment building ended in deadly violence on the evening of October 29, 2023. Surveillance video shows a confrontation in the hallway of the Flatbush Gardens complex between the family of 27-year-old Chin Wai Mode and their downstairs neighbor, 47-year-old Jason Pass. During the encounter, Pass produced a firearm and shot both Mode and his 47-year-old stepfather, Bladimy Mathurin; both men died.

A manhunt for Pass began after the shooting. On the morning of November 1, police located him; when officers confronted him he reportedly lunged with a knife and was fatally shot by police. Family and community members described Mode as a devoted son and Mathurin as a hardworking father. What did neighbors or anyone present that night notice about how the argument began or escalated?
