Baltimore County Police send the NYPD a fax alerting them to Brinsley and his intentions. By the time it filters down to the rank-and-file, he has already struck.
2.47pm
Brinsley identifies his targets in the Bedford-Stuyvesant area of Brooklyn, tells passersby to watch, then fires four shots at them.
As he flees he confronts two Con Edison drivers, who chase him in their truck and point officers in their direction.
He runs into the Myrtle/Willoughby G train station, where he shoots himself dead on the platform
Describing the final moments, caught on surveillance cameras, he said: 'We have found on one of our videos two males who spoke with the perpetrator just prior to the event.
'He asks them three things: For their gang affiliation, he asks them to follow him on Instagram, then he says "watch what I'm going to do".
'He then walks north down on Tompkins, past the two officers in the car, circles back around, goes across the street, then comes up behind the officers.'
