Community in shock after 'horrifying' Brisbane crash
The teenage driver allegedly went through a red light, ploughed into a truck before hitting and killing the couple who were crossing the road.
Witnesses of a horror crash in Brisbane, which left a couple and their unborn baby dead, have described the incident as '"shocking" and "horrifying".
A makeshift memorial has been set up at the scene in Alexandria Hills where a 31-year-old pregnant woman and her 37-year-old partner were killed when they were hit by a car allegedly being driven by a teenager.
Police allege a 17-year-old was driving the stolen Landcruiser 4WD when he went through a red light and ploughed into a truck.
The boy was arrested a short time later after being held to the ground by a local resident when the teen allegedly tried to run from the scene.
He is due to face court today charged with murder, burglary and dangerous driving.
The community are also searching for the couple's dog, Frankie, who disappeared from the scene last night.
It's alleged the 4WD was stolen between 4pm and 5pm yesterday from a Cleveland house, prior to the deadly rampage.
Moments earlier, the 4WD was filmed appearing to engage in a road rage attack, deliberately colliding with a silver Hyundai at the intersection of Vienna and Finucane Roads before speeding away.
About 15 minutes later, he allegedly lost control of the car after speeding through the red light at Finucane Road and Vienna Road and collided with the truck.
The Landcruiser rolled and struck the two victims, killing them both.
The teenage boy allegedly fled the scene of the crash just after 5.30pm and stole a set of keys from a Kingston Avenue house and tried to start a car in the garage.
The home's resident crash tackled the boy in nearby Chelsea Crescent and held him down before police arrived.
"I saw him walking across the lawn, acted like I was going to run him over, stopped, jumped out," the resident said.
"Got him on to the ground. He went to get up so I give him a kick or two, put him on his face and held him until the police arrived."
The driver was arrested and taken to hospital for minor injuries.
Police have described the incident as "absolutely horrible".
"Our thoughts are with their friends and family and in fact, even the local community where the accident occurred," Queensland Acting Chief Superintendent Chris Stream told Today.
"Something that we know was absolutely avoidable and is a horrible situation."
He said the scene was "tough" for first responders and witnesses and "those police officers that had to give those horrible messages to the families of the victims".
The 17-year-old Waterford West boy has been charged with two counts of murder, one count of dangerous operation of a vehicle (adversely affected by an intoxicating substance), two counts of burglary and one count each of unlawful use of a motor vehicle and attempted unlawful use of a motor vehicle.
He'll face Brisbane Children's Court later today.
