Police are keen to speak to 58-year-old Kieran McLaughlin in connection with the death of Barry McCrory in Londonderry last Thursday.
The 35-year-old was shot in what police called a "brutal execution" in a top-floor flat above a city centre cafe on Shipquay Street.
A manhunt - one of the biggest seen in the region in years - was launched last week and has now entered its fifth day as authorities in Northern Ireland and the Republic continue their searches.
His family have now made a direct appeal through police.
Detective Chief Inspector Ian Harrison said: "We're not prejudging Mr McLaughlin, but if he's watching tonight, I would ask you make contact with police immediately on 02871210775."
Mr McLaughlin, if you are watching, please make contact on the number provided.
Police have released a photograph of Mr McLaughlin and urged people not to approach him as he is still at large - and could be armed.
Armed gardaí surrounded a house in Co Donegal on Friday, close to the border, amid reports he was inside.
The operation lasted over 15 hours, but no-one was found in the property. There have also been unconfirmed sightings of Mr McLaughlin in Derry.
"This whole incident has caused a significant degree of concern within the local community," DCI Harrison added.
"We have been liaising closely with Mr McLaughlin's family - they wish to see this come to a peaceful conclusion and that is our wish too."
