Police do not believe that Qin Wu was the intended target of a shooting in Guildford earlier this year.
DETECTIVES investigating the murder of Chinese National Qin Wu at Guildford earlier this year, have appealed for public help to identify who else was inside the home at the time.
Emergency services were called to a home on Kennedy Street at 11pm on February 1 and found Mr Wu suffering a gunshot wound.
Despite the efforts of NSW Ambulance paramedics, the 37-year-old died at the scene and police formed Strike Force Buttle to investigate his death.
While police are still piecing the circumstances together, detective sergeant Justin Moynihan sayd they don't believe Mr Wu was the intended target.
"It is possible Qin may have been shot when he intervened in an argument between his friend and a group of men who arrived during their visit at the house," he said.
"At the time of the incident, the house was also being used as a temple, so there were numerous visitors every day and we would like to speak to anyone who visited in the days leading up to his death."
He said forensic evidence also indicates someone else was also shot during the incident.
"We believe at least two people left the house after the shooting and returned a short time later with a third person, but they weren't on scene when police arrived, neither was Qin's friend," Det Sgt Moynihan said.
"Despite numerous inquiries with hospitals and medical professionals across Sydney, we have not been able to locate the injured person and have concerns for their welfare.
"Ultimately, someone out there knows something, and they might be concealing an offence. Now is the time to come forward."
