Father mourns lost son

A distraught father has remembered his son as a "good-looking jovial" kid after the 20-year-old was killed in a car crash in Hilton yesterday.

Peter Liebeck was one of three people to die in a horror 24 hours on WA roads.

Geoff Liebeck said his only child worked alongside him at a pet shop but dreamed of starting an apprenticeship.

"I'll miss him. He was a jovial person and he had many friends," Mr Liebeck said.

The force of the two-car collision at the intersection of South and Carrington streets sent tyres and glass from one of the vehicles 40m from the crash.

Mr Liebeck died instantly. Ben Brown, 23, died from his injuries. Both men were rear passengers in a Mazda that collided with a Ford Falcon utility.

Two others in the Mazda, including the 29-year-old male driver, had minor injuries. The ute driver was also taken to hospital.

Just hours later, a 70-year-old man died when his station wagon rolled 5km west of Mullewa.

About 11.40am, an 86-year-old man on a gopher was hit by a car when he tried to cross Acanthus Road in Willetton.

The man, known to neighbours as "Old Tom", was in a critical condition in Fremantle Hospital last night.
