MENDHAM BOROUGH, N.J. — The Bank of America executive killed in a random, unprovoked stabbing in New York City’s Times Square last week was laid to rest Wednesday as hundreds of mourners turned out to pay their respects over the past two days.
Erin Guiltinan Piacenti, 32, of Chester, New Jersey, had just returned from maternity leave after the birth of her first child when police say a woman with a history of mental illness stabbed her and another bystander on Seventh Avenue.
Piacenti, the oldest of five siblings, graduated from the University of Pennsylvania and the Fordham University School of Law, according to her family’s death announcement.

She became the music director of UPenn’s Dischord A Cappella group and met her husband, Frank Piacenti, at law school, according to the obituary. The two married in 2024 and welcomed their first and only child, Madison, in March.
After graduation, she worked at the Manhattan-based international law firm, Davis Polk & Wardwell, before becoming a vice president at Bank of America.

Aug. 31 was also her first day back from maternity leave, according to the organizer of a GoFundMe campaign that has raised nearly $1 million as of Tuesday for 6-month-old Madison.

Just before 4:30 p.m. on Aug. 31, Piacenti was stabbed in the abdomen in New York’s Times Square, according to NYPD Commissioner Jessica Tisch. The injury proved fatal.
Speaking with reporters on the evening of the murder, Tisch identified the suspect as 49-year-old Queens resident Pamela Cisneros.
