In September 2022, police appealed for information on a man seen in Aberdeen's Wilson's Sports Bar in 2015, saying he was in his 60s or 70s and wearing an Iron Maiden T-shirt.

[2] To make ends meet he took up work as a taxi driver, although he didn't particularly like the job and his wife worried about his safety on night shifts.

[2][3] At around 8:30 pm, his Ford Cortina car was seen parked in the busy Queen's Road in Aberdeen as he picked up a fare in his taxi.

[2] After driving 2 miles (3 km) in his taxi towards Culter, he turned onto Pitfodels Station Road, just on the outskirts of the city in Braeside, where his vehicle stopped.

[2] The callousness of the killer was noted, with him having brought a cheese wire out with him that night, presumably to attack someone, and having killed a man who always said he would never try and fight a potential robber.

[2] The police launched a massive manhunt to find the murderer at the time, visiting 10,000 homes and taking 8,000 statements.

[2] A sighting of a man with blood on his hands was made shortly after the murder at the local "Mr Chips" takeaway on the Great Western Road.

[2][3] Dozens of people came forward with new information, and Crimewatch Live released a statement saying "The George Murdoch case has clearly struck a chord".

[3] In September 2022, police revealed they wanted to trace a man seen in Wilson's Sports Bar in Aberdeen in 2015 wearing an Iron Maiden T-shirt, saying that they believed he may be able to help with the inquiry.

[4] The lead detective on the case, James Callander, said: "Following last year's appeal we now have information about a man we would like to speak to as we believe he may be able to assist with our investigation into the murder of George.

The public's continued assistance and support is vital in order to bring this inquiry to a conclusion and provide much-needed closure to George's family.

"[4] In September 2023, police revealed that they had isolated what is believed to be the DNA profile of the male killer, which has been described as the "most significant development in the case to date".

We can take a simple DNA swab and we can compare that to give peace of mind to the family to say your father isn't responsible".
