Two teenagers are dead and four others are in hospital after a horrific crash in Perth on Thursday night.
As friends and loved ones placed flowers in tribute on Friday, police launched an investigation into what went so tragically wrong.
Police say six teenagers were in the car when it struck a kerb on Lake Road in Seville Grove and hit a tree around 10pm.
Those first on the scene say at least one of the boys had been flung out of the sedan by the force of the crash.
A 15-year-old passenger was taken to Armadale Hospital but his injuries were so severe he could not be saved.
Another passenger, a young man of 17, died at the scene.
The 18-year-old driver was taken to Royal Perth Hospital with minor injuries and three others were taken to hospital as a precaution.
“Everyone was in shock, all the onlookers were in shock,” a Seville Grove resident told 7NEWS.
“It’s quite a small community as well, a of the locals know each other, so to have such young people in the area in such a tragic accident, it’s really heartbreaking.”
Many of those who came to pay their respects at the crash site were classmates from Kelmscott Senior High School.
One of the teenagers killed is a young relative of Rita Saffioti, WA’s transport minister.
So many people attended the crash site to lay flowers and pay respects on Friday that police were called in to manage traffic and keep those in mourning safe.
