Another horror accident on Perth roads last night claimed the life of a woman and launched a search for the driver of another car.
The woman was killed when her car was cut in two about 10pm in Orange Grover.
Police said her car was T-boned at the corner of Tonkin Highway and Gosnells Road East about 10pm and the other driver left the scene.
Surrounding streets were cordoned off as police and the dog squad searched for the other driver.
A man later went to Armadale Hospital with leg injuries but it was unclear if he was the driver.
The fatality takes WA's road toll for the year to 26.
Also yesterday, the devastated wife of a man whose car ploughed into a tree - killing himself and two passengers in Morley on Friday night - spoke of her grief and of how her two sons are too young to realise their father is not coming home.
Michelle Cook, wife of Jason Lee Cook, 43, said she was truly sorry for the accident that killed her husband and Steven James Formato, 31, and Craig Leslie Kenney, 34.
The men were going east on Morley Drive about 11.40pm when their Holden Commodore hit a tree on the median strip, cutting the car in half and sending debris up to 50m.
Ms Cook said she would have to start a new life without her partner of 23 years.
"I've been with him longer than I've been without him," she said. "He was a good man and he loved his kids and we've been together for ever."
The men had known each other for many years, living within 2km in Morley, Dianella and Noranda.
It is understood they were drinking together before the accident though police could not confirm reports they were at a party.
Police are investigating if speed, alcohol and drugs were factors and early estimates put the car's speed at 140km/h.Police are also investigating a crash which left a 22-year-old woman fighting for her life after the car she was driving on Beeliar Drive, Beeliar, about 7.15am yesterday hit a stationary water truck.
