Crash driver was on drugs

The man jailed for causing the deaths of a taxi driver and his passenger when he sped through a red light in a stolen car has also admitted being on drugs at the time of the tragedy.

Antony Edwards Fogarty is serving a long jail term for the deaths of Kuldeep Singh and Sean Barrett, who died after being crashed into by Fogarty as he tried to evade police in October 2012.

At an intersection in Kewdale, Fogarty crashed into Mr Singh's taxi, killing the father-to-be and his passenger Dr Barrett, who had arrived in WA just an hour earlier.

Fogarty was jailed for 11 years for the manslaughter of both men, but is set to appeal against the sentence.

He is facing more punishment, after pleading guilty in Perth Magistrate's Court to driving under the influence of drugs, driving while suspended and driving more than 45km/h over the speed limit at the time of the crash. Blood tests showed he had amphetamines and cannabis in his system.
