Robby Fabbri had a goal and two asissts, Gustav Lindstrom had a goal and an assist, and Ville Husso made 29 saves for the Red Wings (24-20-8), who have won three straight, including 5-2 against the Canucks in Detroit on Saturday.
Larkin, however, didn't want to talk about the game, instead wanting to speak only about the mass shooting that occurred at Michigan State University on Monday night.
"This is pretty sobering dealing right now with tonight, coming into the locker room hearing the news and we're all just pretty, pretty devastated by it and our thoughts and prayers go out to everyone involved, all the students, all the families," Larkin said, his voice breaking. "It just hurts the heart and we feel for everyone involved.
"I know tonight was a win, but it's kind of hard to talk about anything else. We're all thinking about our home state right now."
Sheldon Dries scored, and Collin Delia made 17 saves for the Canucks (21-29-4), who are 1-3-1 in their past five games. It was the 25th time in 54 games this season that Vancouver has given up five or more goals.
"We're going to have to go back to grade school on how to defend, how to stop and start because too many guys are spinning," said Canucks coach Rick Tocchet, who is 3-4-1 since taking over for coach Bruce Boudreau on Jan. 22. "We're a very high-risk team. You've got to take pride in defending, you've got to take pride in blocking a shot or getting the puck out. You've got to have that pride."
The Canucks were coming off a four-game road trip and played their fifth game in eight days, but Tocchet wasn't interested in excuses.
"Structure, discipline, leadership, they get you through these games when you just maybe don't have your best," Tocchet said. "If you don't have your legs, then you've got to play smart hockey, don't chase the game."
Larkin made it 1-0 on a breakaway at 10:58 of the first period. Red Wings defenseman Moritz Seider deflected a pass by Vancouver defenseman Oliver Ekman-Larsson in Detroit's zone, and Larkin won a race with Elias Pettersson and Luke Schenn before tucking a deke between Delia's pads.
"Energy, spark," Red Wings coach Derek Lalonde said of Larkin. "He was flying early on."
