Jacob and four teenage mates were allegedly targeted by the 20 year old female driver, who has been charged with Jacob's murder.

Police believe the shocking incident was sparked by a pre-arranged fight between two teenagers at a park two kilometres away.

That small brawl kicked off a chain of violent and unprecedented events, with WA Police still trying to piece together exactly what happened.

At 3pm on Thursday, two teenagers - one from Canning Vale College, one from a Mandurah high school - arranged to meet in a Canning Vale Park after school for a fight.

Within minutes, the commotion spilled out into the car park of a nearby bottle shop.

Then, the car rammed into Jacob Cummins and his friends on Eucalyptus Boulevard.

The markings left behind on the road are a confronting reminder of what happened there.

Police allege that the 20-year-old woman mounted the curb and drove at the five teenagers, hitting them at speed before stopping approximately 50 metres further down the road.

She has been charged with murder, plus four counts of attempting to unlawfully kill.

She will face court on Saturday.

The tragic events have left countless people traumatised, including many young teenagers who never expected an after-school fight to end in such tragedy.

A caller to 6PR Mornings expressed concern over the number of knives that students were carrying at school, describing it as "mind-blowing".

Canning Vale College did not comment on the incidents on Friday but the Education Department said a student services team, including counsellers, attended the school to help calm down the situation.

Police said they are speaking to all the parties involved to make sure there is no further violence or any retaliation, but officers say they are prepared if there is.

Several teenagers remain in different hospitals across Perth as police continue to gather information on the sequence of events.

Two 16-year-olds are in a stable condition after surgery at the State Trauma Unit, one with both legs broken.
