Backpacker killer's jail term increase

Victim Kristopher Dixon.

Prosecutors have won an appeal against the "inadequate" 4 ½ -year jail term handed to a French backpacker who fatally stabbed a man in Broome.

Thomas Camus, an accountant who was backpacking in Broome, was acquitted of murder by a Supreme Court last year but convicted of manslaughter after stabbing Kristopher Dixon during a drunken fight on Christmas Day 2011.

He had stabbed the victim three times with a knife.

Today, the Court of Appeal boosted his jail term to six years and six months after ruling the penalty had not reflected the seriousness of the crime.

The original sentence had been handed down by Chief Justice Wayne Martin who had taken into account Camus' youth and clean record.

The jail term had sparked angry responses from the victim's family inside the court.

Camus remains eligible for parole and the sentence remains backdated to the day of the killing.

He can now apply for release after serving four years and six months.
