After a strong outing at the King City Classic in Cleveland at the beginning of the month a number of schools began recruiting the 6-foot-2 combo guard.
On Sunday, Demps put his recruitment to bed, giving Northwestern a verbal commitment.
"I just felt academically it was the best fit seeing that I want to get into journalism," Demps told Scout.com. "Also Northwestern is a place where I have a good chance of coming in and starting right away".
"I also feel like with the pieces we have coming in, we can compete for a Big 10 championship."
