Students gathered at Springbank Community High School on Friday afternoon to share their grief for two classmates killed in a car crash early Thursday morning.
Flowers were left at a roadside on Range Road 32, where the crash occurred.
Two other teens also injured in the crash remain in hospital. No update was immediately available on their condition.
Sixteen-year-old Josh Lyszkiewicz attended the school with the girls. He said he went back today to offer support.
"Just, you know, see my friends again, and I'll just talk with them and, you know, try to get over this together," Lyszkiewicz said.
"Because, you know, we're all going to get through it. But it's going to be hard."
Chloe Fisher, 17, was laying flowers at the scene, not far from the school.
"They were so kind and gentle, and they didn't deserve what happened to them," she said. "It's just, it's so tragic. I don't even really know what to say."
One of the girls who died was Daniela Nicoletti, while her sister, Giulia Nicoletti, is in hospital. One other girl was killed and another is in hospital, but their names have not yet been confirmed.
All the occupants of the vehicle were female and 16 to 17 years old.
A spokesperson with Rocky View Schools said the school division would continue to offer support to students and staff in the coming days and weeks.
RCMP previously told CBC News that the vehicle had rolled off the road.
Anyone with information or who may have witnessed the crash is asked to call the Cochrane RCMP at 403-851-8000 or send a tip anonymously to Crime Stoppers.
