A 21-YEAR-OLD from Rochester continues to fight for his life following a four-person fatality at Burramboot on Saturday night.
An 18-year-old from Bendigo and his 19-year-old passenger from Elmore, and a 53-year-old and 52-year-old, both from Rochester, were killed in the collision.
A 21-year-old from Rochester remains in a critical but stable condition at the Alfred Hospital following the collision.
An 18-year-old, also from Rochester, is in a serious but stable condition at the Royal Melbourne Hospital. A 28-year-old sustained minor injuries and has been released from hospital.
Police are investigating speed, alcohol and irresponsible behaviour as possible causes of the crash.
The head-on collision occurred just before 10pm on Saturday on the Heathcote-Rochester Road in Burramboot.
Two teenagers were travelling south in a Holden sedan, which veered off the road and collided with a 4WD travelling in the other direction.
Assistant Commissioner Robert Hill said "excessive speed" and possibly alcohol had been a factor, with witnesses also reporting "hoon behaviour" shortly before the crash.
He said it was believed the young driver of the Holden and his passenger had been consuming large amounts of alcohol throughout the day at a nearby campground.
Just after 9pm, they were seen in the nearby vicinity "driving erratically".
"After that point the driver has driven at excessive speeds and lost control of the vehicle," he said.
“There are matters ... that would indicate that we have causal factors including alcohol, speed, irresponsible behaviour on behalf of one of the drivers.
"The five people in the other vehicle were going about their business and two of them have now lost their life."
All five men in the 4WD worked as fruit pickers in the nearby area and were driving home from a trip to Melbourne.
Assistant Commissioner Hill said a local orchard farmer witnessed the crash and pulled the surviving passengers out of the burning wreckage.
