At around 7.20pm on Monday 17 April 2017 officers attended a house on Blackburn Street, Trinity and found the body of a man.
The man, who has since been formally identified as 61-year-old Giorgio Roncari - also known as Guiseppi - suffered injuries which officers are treating as suspicious.
Paying tribute to him, Giorgio’s family said: “It is a great loss of a twin brother with a big heart, a protective and loving uncle, a brother-in-law who was like a brother.
“We will miss you very much; you have left an unbearable emptiness.”
Officers are continuing to appeal for anyone who has information to come forward.
Detective Inspector Andy Butterworth of GMP’s Major Incident Team, said: “While Giorgio’s family are dealing with the extremely painful news, we are investing our time in actively searching for those responsible for his death.
As always, if you have information you can contact the investigative team directly or if you would prefer, you can remain anonymous.
Each piece of information will be dealt with the strictest confidence and however small you may think it is, it may prove to be significant in understanding what happened to Giorgio.
Anyone with information should contact police on 0161 856 5351 or the independent charity Crimestoppers, anonymously, on 0800 555 111.
