Min Ai, a 40-year-old woman, was killed on the morning of October 26, 2020, on a Lower Manhattan street as the workday was beginning. It happened near the Financial District, in the area of Greenwich Street and Morris Street by a subway entrance, where scaffolding cast a harsh shade over the sidewalk. In the first stunned moments after the shots, people nearby tried to make sense of what they’d heard—quick cracks that didn’t sound like construction—before realizing someone had been hit.
A witness later described her as appearing Asian.
Police said her estranged husband, Xin Yu, had been waiting outside her apartment area just after 9 a.m., and that an argument erupted when he confronted her as she set out on her usual path toward work. The violence, investigators said, wasn’t only gunfire: they reported that he slashed her with a knife and then shot her in the head and torso. On the street, the attack unfolded in moments, the kind of sudden brutality that leaves bystanders frozen—some hearing the sequence of shots, others rushing toward the sound and finding her motionless.
Officers responding to the 911 call found both Min Ai and a 46-year-old man shot; the firearm was recovered near him, and authorities concluded it was an apparent murder-suicide. Reporting on the incident described two shots striking her in the head, and the man suffering a gunshot wound consistent with having turned the weapon on himself at close range. The scene was sealed off for hours as detectives worked, but police indicated early that the facts pointed to a closed loop—one assailant, one victim, and the assailant dead at or shortly after the scene.
Investigators and reporting indicated the marriage was unraveling and that she had been planning a divorce, with officials saying she had been living apart from him. Police also said she had been secretly dating a colleague for about a year, and that the colleague contacted detectives after he couldn’t reach her, helping investigators piece together her recent life and the tension surrounding it. Authorities said Xin Yu lived in Ontario, Canada, and they believed he came to New York to confront her.
Because the suspected killer died, there were no arrests, charges, or later court proceedings connected to a surviving defendant. The case, as described by police and contemporaneous accounts, ended where it began—on that stretch of Lower Manhattan pavement—leaving only the aftermath: a daylight killing, a suspected domestic-violence motive tied to separation and divorce plans, and a community forced to absorb how quickly an ordinary Monday morning turned irreversible.
