Police on Tuesday identified the man behind the series of attacks Monday morning across Manhattan that left 3 people dead as 51-year-old Ramon Rivera.

A third person has died, this one a 36-year-old woman, after a man with a history of mental health issues allegedly went on an unprovoked stabbing spree in Manhattan a day ago, felling people just going about their morning routines.

Three unprovoked stabbings across Manhattan Monday morning left two men dead and one woman “fighting for her life,” according to the New York City Police Department. A man is in custody, police said.
