Detectives today appealed for "courage" to help find the person who stabbed a much-loved chef to death in his back yard.
Colin Hughes was murdered almost 10 years ago as he went to investigate a noise at the back of his property in Old Swan.
The 42-year-old suffered a single knife wound to his chest, just before 1am, on September 21, 2010, and died a short time later.
Ten people have been arrested and questioned over the killing on Baden Road, but nobody has been charged.
Today, police urged people to come forward to help solve the tragic crime, and officers are focusing on two lines of enquiry.
They are keen to trace a white man, 5ft 10 in tall, of slim build, wearing a dark coloured tracksuit, who was seen in the alleyway behind Mr Hughes’ home just prior to his death.
Detectives also want to speak to the occupants of a dark coloured hatchback who spoke to Mr Hughes outside his home, at about 8.30pm the previous night.
Two years ago, Mr Hughes' fiancee, Paula Greenwood spoke of how she will "always love him," describing him as a hard-working family man who "loved his children."
Colin known to friends as “Yosser” – after the character in Boys from the Black Stuff – was well known in Old Swan, where he lived, grew up and worked as a chef.

Paula said: "I still love him and I will never, ever forget him….
"He was always on the go, the type to get up out of bed, have breakfast and be out the door.
"In all the years we were together there was never any hassle, he was just a lovely man."

Colin's mum, Margaret, previously said: "He will always be in my heart.
“His dad John would say if you could bottle his charisma, he would make a fortune – he lit up the room when he walked in.
“He could not walk down the street without saying hello to someone and I have been told by many friends he would always stop and help them with their shopping.”
Merseyside Police has appealed for information on the Crimewatch Roadshow programme, this morning.
Detective Chief Inspector Mark Baker said: "It’s nearly 10 years since Colin Hughes was murdered at his home address in Old Swan and we remain determined to find those responsible and allow his family to finally have some closure.
"We know that loyalties change over time and I would hope that anyone with information can find the courage to come forward to tell us what they know. We understand that people are sometimes reluctant to come forward in the aftermath of such a serious crime as this.
"I would like to take this opportunity to appeal once again to the community for their help with the investigation and would urge anyone with information to come forward either directly to the force or anonymously through Crimestoppers in the strictest of confidence.
"No matter how small the piece of information is, it may prove vital to the investigation.
