Friends of two teens killed in a crash in Aurora are mourning the second road tragedy to hit students at one Vaughan school in less than a month.

Ryan Sheridan, 17, and Niko Di Iorio, 15, died when their Volkswagen Jetta spun into a ditch and hit a tree on Keele Street, south of Lloydtown-Aurora Road on Monday afternoon.

A third boy, 15, is in hospital, and is expected to survive. Monday was a P.A. day, and the boys were heading to a ski hill to go snowboarding.

Teens at Saint Joan of Arc Catholic High School in Vaughan told CTV News all the boys were students there.

One boy said classmates were crying in the hallways when they heard the news.

"It's really sad someone my age, a little bit older than me can die off this fast," one student said.

Grief counsellors were at the school Tuesday to help classmates deal with the deaths.

York Regional Police say the cause of Monday's crash is still under investigation, but they suspect high speed was a factor.

"What we have here is simply a high-speed collision," Const. Mike Buchanan told reporters Monday at the crash scene. Police do not believe the boys were street racing.

This is the second tragedy for kids at the school in less than a month.

Grade 12 student Steven Seixeiro, 17, was struck and killed by a tractor-trailer as he transferred buses on Jan. 12.

He was one of the 14 people killed in a rash of pedestrian deaths in the GTA in January.
