Drew Crawford scored 19 points and blocked the potential tying 3-pointer at the buzzer to lead Northwestern to a 63-60 double-overtime victory over Purdue hours after a shooting on the Boilermakers' campus on Tuesday.

Crawford scored four points in the second OT and delivered the big block on Ronnie Johnson off an inbounds pass as time expired to preserve the win.

Tre Demps added 19 points, and the Wildcats (10-10, 3-4 Big Ten) prevailed on an emotional night for the Boilermakers (13-6, 3-3).

An engineering student opened fire inside a basement classroom at Purdue earlier in the day, killing a teaching assistant, and there was a moment of silence before the game.
