New York Daily News: MANHATTAN, NY – A 40-year-old woman shot dead by her husband in Manhattan’s Financial District told a man she was dating she wanted a divorce from her mentally ill spouse, police sources said Tuesday.

It wasn’t clear if victim Min Ai’s husband, Xin Yu, 46, knew about her boyfriend or divorce plans. But on Monday morning he confronted her at Morris Street and Trinity Place and shot her.

He was carrying their marriage certificate when he shot her, sources said Tuesday.

After she hit the ground he lifted her head up and fired a second time, before turning the gun on himself and pulling the trigger, a source said.

Her husband died a short time later at New York-Presbyterian Lower Manhattan Hospital.

Ai lived in Battery Park City and worked at a nearby Broadway bank. She was apparently headed to work when Yu confronted her.

Yu lived in Ontario, and it wasn’t clear when he came to the city.

The boyfriend, who works at the same bank as the wife and lives in New Jersey, told detectives he was worried when he called her Monday morning and could not reach her, sources said.

He had been dating for more than a year and tried to keep their relationship secret from co-workers, entering and leaving the bank at different times, sources said.
