Gregory Castillo Volquez was stabbed to death in a “brutal” attack in an alley on Tiverton Road around 5am on January 13.
Two men have been charged with the 36-year-old’s murder, but police say more information is needed to help the investigation.
Speaking today (March 12) outside the address where the murder took place, Detective Chief Inspector Jim Barry, said: “This violent attack ripped a father away from his two children.
“Since January, the incident has massively impacted those close to Gregory and local residents.
“This is why it’s imperative we work together to secure justice.
“Anyone with information must share it with us, no matter how small they deem it to be.
“We are committed to working alongside those who provide statements throughout the judicial process.”
Gregory’s family, who are being supported by officers, added: “Gregory was a much-loved son, father and friend, and his family is heartbroken by this loss.
“Even the smallest detail could be crucial. Please come forward and help us get justice for Gregory.”
Officers believe there may have been people in the area who witnessed the attack and have valuable information but have not come forward.
They reminded the public that information can be submitted anonymously if they do not feel comfortable speaking to the police.
The public is urged to contact the police via 101 or anonymously via Crimestoppers on 0800 555 111, quoting 809/13JAN.
