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.

A man who officials say carried out a string of stabbings across a swath of Manhattan has been charged with three counts of murder.
