Norris expressed his thoughts after a 15-year-old boy allegedly shot and killed four students and injured several more Tuesday at Oxford High School, about 30 miles north of Detroit.
"You never really think something like this is going to happen in your hometown," the 22-year-old said.
"Thinking of just what some of those kids went through, the parents of those kids. It's really difficult. All I can do is send my thoughts and my love. I'm proud to be from there. It's such an unfortunate situation."
Norris wore a patch that included "Oxford" and the number 42 on his jacket at the media availability before the Senators hosted the Vancouver Canucks.
Ottawa forward Brady Tkachuk said he has tried to support Norris following the incident. The Senators captain was Norris' teammate with the USA Hockey National Team Development Program, which is based in Michigan, during the 2016-17 and 2017-18 seasons.
"I was actually with [Norris] when he found out," Tkachuk said. "We've driven by that high school before, so we're definitely thinking about the people involved and all the people that have been affected. It's an important time to be there for Josh."
The shooting was addressed by Detroit Red Wings captain Dylan Larkin and coach Jeff Blashill after their 2-1 win at the Boston Bruins on Tuesday.
"I'd like to, on behalf of our whole organization and the guys in our room, send our heartfelt condolences to the community of Oxford, Michigan, and metro Detroit and the state of Michigan," Larkin said.
"It was an unspeakable tragedy what happened today."
Larkin is from Waterford, Michigan, about a half-hour from Oxford.
"It hit us hard. It hit the guys in the room hard," Larkin said. "We're thinking about the victims and the entire community. We're there to support and we just feel awful for the tragedy that happened today. Our thoughts are with Oxford, Michigan."
Blashill, who was born in Detroit and has been Red Wings coach since 2015-16, became emotional while expressing his disbelief about the shooting.
"I just want to send out my prayers to the families that were affected today in Oxford," Blashill said. "It's a terrible, terrible thing. It just shouldn't happen.
"Nothing I say certainly can do anything to help those that suffered a tragedy, that lost their lives. I think it's insane that this is somewhat normal. It just shouldn't happen. My heart goes out to certainly everybody involved, everybody at the school, the community. It's got to stop."
