Mikolaj Wilk (35) and his partner are originally from Poland
Cork gardaí have recovered a gun as part of the investigation into the murder of Mikolaj Wilk.
The 35-year-old, also known as Nick, was murdered in his home at The Bridge House, Maglin in Ballincollig on Sunday morning.
His partner who is in her early 30s, was also admitted to hospital for non-life threatening injuries.
They are both originally from Poland.
Gardaí responded to an incident at 3.17am on Sunday and were on the scene in less than five minutes.
The assailants had fled the scene at that time, with the direction of travel or mode of transport unknown.
Gardaí found Mr Wilk seriously injured with life threatening injuries, and gave medical attention while awaiting the arrival of the paramedics.
He was removed to the Cork University Hospital, where he died of his injuries.
Following a technical examination of a BMW car located in Iniskenny, Ballinora, Waterfall, gardaí have recovered the firearm which will now be sent for further examination.
The scene at The Bridge House is still currently preserved, and gardaí are carrying out house-to-house enquiries.
