Slain chef's family angry over sentence

Supporters of slain Sydney chef Patrick Crowe have staged an angry protest after a teenage girl escaped jail time for her role in his stabbing death.

Mr Crowe, 22, was set upon by a gang of young people after he and his friends exchanged barbs with a group of young women.

The gang of mostly teenagers circled Mr Crowe, punching and kicking him, before 22-year-old Christopher Brilliantes stabbed him twice with a knife at a Parramatta bus stop on July 8, 2012.

A 16-year-old girl, who cannot be named for legal reasons, was due to stand trial in the Supreme Court last year charged with murder.

The murder charge was dropped but an affray charge remained.

Family and friends of Mr Crowe were furious that the girl was given a 10-month supervised probation order at Parramatta Children's Court on Friday.

No conviction was recorded and she is required to be on good behaviour.

Mr Crowe's mother Angelina Crowe said the law needed to be changed to make young people accountable for their actions.

"She may not be the one who stabbed my son but she was definitely the one who pointed out who was going to be stabbed," Ms Crowe told reporters outside court.

"He was a beautiful young man, he loved life, he loved people and he shouldn't be dead."

A large group of friends and family held placards outside court that read "murder should equal life sentence" and "murder is murder, no matter of age" after the teenager was sentenced.

Brilliantes was jailed this month for at least 13 years and six months for murder.

The court has previously heard that seven other teenagers had already been dealt with for offences including affray and concealing a serious indictable offence.

Most of them received good behaviour bonds.
