Eight days before, the Panthers were on the road to play the Vancouver Canucks. Luongo came off the ice after the morning skate and found a notification on his phone. His 7-year-old son, Gianni, had his school on lockdown.
Luongo soon learned there was a shooter at Marjory Stoneman Douglas High School in Parkland, less than a mile from Gianni's school; 3 1/2 miles from the Panthers' practice rink in Coral Springs, Florida; and 13 1/2 miles from BB&T Center.
Gianni spent three hours hiding in a closet with his classmates. He was safe. So was Luongo's wife, Gina, and 10-year-old daughter, Gabriella, who was out of school because of a doctor's appointment.
Seventeen people died -- 14 teenagers, three adults.
This was the Panthers' first home game since. When coach Bob Boughner heard Luongo was going to give a speech in the pregame ceremony, he was worried. He asked Luongo if he was comfortable with it.
"He wouldn't take no for an answer," Boughner said. "He said, 'No, this is something I've got to do.' "
And so, in the same arena where CNN held a town hall meeting Wednesday, Luongo spoke from the heart.
"I didn't want to have anything scripted," Luongo said afterward. "I just wanted to let it come out the way it was meant to be."
To the families of the victims …
"It's heartbreaking," Luongo said. "You guys are in our thoughts. We've been thinking about you every day constantly for the last week, and just know that we're there for you if you guys need anything. You'll be in our prayers, and let's try to move on together."
To the teachers who put themselves in harm's way …
"Some of them didn't make it trying to protect children," Luongo said. "That is truly what a hero is."
To the students who have spoken out …
"I'm very, very proud of you guys," Luongo said. "You guys are brave. You guys are an inspiration to all of us, and at the end of the day, you guys are what's giving us hope for the future."
In the stands were most of the Stoneman Douglas varsity and junior varsity hockey teams. One player, Jesse Guttenberg, lost a sister, Jaime.
"Tears, tears, tears," said Bonnie Hauptman, the manager for both teams, who has two children who go to Stoneman Douglas. "Just hearing him speak and how deeply affected he is being a resident of the community, having children himself, you know …
"There are no words for what we went through, and everyone feels it. But when children are involved and you can put yourselves in someone's shoes and think about, 'That could have been my child' …
"He is very moving."

Other Panthers players live in Parkland and have kids in school. Some Panthers staff members are Stoneman Douglas alumni. Boughner said everyone seemed to know someone affected.
They wanted to do what they could.
"Our privilege is to steward this team for the benefit of the community, for the benefit of everyone in the community across the county," Panthers owner Vincent Viola said. "The Florida Panthers should represent what is the best of our community."
The Panthers organized a blood drive to replenish local banks. Eight OneBlood buses parked in the lot at BB&T Center on Thursday, each with four beds, allowing people to donate from 12-7 p.m. Six beds were in the concourse so people could donate from 6 p.m. through the second intermission. They collected 377 pints.
Chairs were full of people -- Panthers and Capitals fans, from places like Fort Myers and Davie and Boca Raton -- waiting for their turns at about 6 p.m., as the sun began to set and the flags flew at half-staff.
Corey Beale, 40, a 1996 Stoneman Douglas graduate, came with his 12-year-old son, Ryan, who attends West Glades Middle School next to Stoneman Douglas. Ryan and his classmates could hear gunshots. They were locked down for more than 3 1/2 hours.
"You never think it happens to you, but when it does, it opens up your eyes," Corey said. "I think it's a community wanting to give back and really support everybody around them -- no matter what it is, unite under a cause for good."
