A 24-year-old man who killed a physicist and a taxi driver in a horror high-speed crash in a stolen car had never held a driver's licence and was so high on drugs he was incapable of safely driving, a Perth court has been told.
Antony Edwards Fogarty drove through several red lights and reaching speeds of up 170km/h while trying to evade police for almost 30 minutes in the stolen car.
The father-of-five then t-boned Kulpdeep Singh's taxi, instantly killing the 28-year-old Indian taxi driver and his passenger, British scientist Dr Sean Barrett.
Mr Singh was taking Dr Barrett - who had just arrived in Perth for a physics conference - from the airport to his hotel when they were killed by Fogarty who ran a red light at Orrong Road in Kewdale.
Police had attempted to stop Fogarty - who was driving a stolen car and was being monitored by the police helicopter - on several occasions, but each time he failed to stop.
The court was told how police described seeing an explosion as the taxi burst into flames.
Fogarty, who has pleaded guilty to the manslaughter of Mr Singh and Dr Barrett, stood up at the end of today's court proceedings to apologise to the men's families who were not present.
"I know it won't bring them back but I want them to know I'm sorry," Fogarty said as he turned to look at the back of the court.
Fogarty faces a maximum sentence of life imprisonment.
Outside court, Fogarty's mother Faye said she was deeply sorry to both men's families for what her son did. She said her son was very sorry and would have live with it for the rest of his life.
At a sentencing hearing in the Supreme Court this morning it was revealed that Fogarty was so intoxicated and high on methamphetamine and cannabis that he was incapable of safely driving a car.
He ran at least four red lights before crashing into the taxi. One red light camera captured him driving at 170km/h.
Witnesses described how after the crash, Fogarty got out of his car but collapsed screaming in pain about his leg and that he was not the driver.
Fogarty, who was treated at the scene for a suspected broken leg, also told paramedics that he was not the driver and that "the bastard ran off".
The court was told Fogarty was recorded on phone calls from prison admitting to relatives that he was the driver.
Defence lawyer Jonathan Davies said his client was remorseful and had positive long-term prospects for rehabilitation.
Prosecutor Theresa Austin argued the case fell into the worst category.
She said Fogarty drove at "manifestly excessive" speeds and grossly contravened traffic laws to evade police.
Fogarty has been remanded in custody to be sentenced in February.
