St. Rita head coach Gary DeCesare confirmed the news.
"He was one of the first guys to come [to St. Rita]," DeCesare said. "I think he believed in my vision of building St. Rita up and I think he thought the same thing with Northwestern when Chris got the job."
"I think the ultimate thing was the vision, the opportunity to help build something special and the prestigious Northwestern academics.
Prior to picking Northwestern, Law, a 2014 recruit, took four official visits. But his trip to Northwestern was an unofficial. In the end, the proximity played a major factor in his college decision.
"I think he believes in Chris' vision of helping Northwestern," DeCesare said. "He has a phenomenal family and his sister plays at Loyola, which is down the block. Now the mom and dad can get in the car and see both Vic and their daughter play."
Law, a four-star recruit, is a 6-foot-7 versatile forward. He can play inside and out, is an impressive athlete and is a quality rebounder.
Law is ranked No. 70 overall in the 2014 class.
