Widow pleads for help in solving husband's murder

THE widow of a slain Sydney security guard has welcomed the offer of a $100,000 reward for information leading to the arrest of the man who gunned down her husband.

Monica Allibon broke down on Tuesday as she told reporters about how the senseless killing of her husband Gary three years ago had changed her life forever.

Mr Allibon was robbed and shot by a group of men armed with handguns when he stepped out of a security van and into the foyer of a building in June 2010.

He was rushed to hospital where he later died.

Ms Allibon said she hoped the NSW Government's reward would encourage someone to provide detectives with the missing links needed to catch her husband's killer.

"My husband was killed by someone who can only be described as a cold-blooded murderer," Mrs Allibon said.

"The murder of someone you love changes your life forever.

"It's nearly been three years since we lost Gary and I feel as empty today as I did the day of his death".

During the attack, the group of male offenders stole cash from the guards and fled the scene in a high performance silver Audi sedan.

Detective Superintendent Luke Moore said any information, no matter how irrelevant or insignificant it may seem, could be the "much needed piece of the puzzle".

Anyone with information can phone Crime Stoppers on 1800 333 000.
