Police carried out a number of enquiries into the murder of David Murphy on Friday as they attempt to establish a motive for the crime.
The body of the 52-year-old was found at his home on the Church Road in Glenwherry last month.
Police visited a large number of locations across Ballymena and Keels on Friday as part of their investigation into his murder. They circulated leaflets appealing for information on Mr Murphy's murder.
PSNI Detective Chief Inspector Geoff Boyce said that Mr Murphy died as a result of gunshot wounds.
"We are working extremely hard to pinpoint a motive for this senseless murder and to retrace David’s steps in the days leading up to the killing," he said.
"We hope that today’s investigative operation will provide fresh leads and new information that will lead us to David’s killers.
"I would ask anyone with information that could help us to please get in touch by calling 101. Alternatively, information can also be provided to the independent charity Crimestoppers on 0800 555 111 which is 100% anonymous and gives people the power to speak up and stop crime.”
A friend of Mr Murphy found him dead at his home after he had been shot twice with what they believe was a shotgun.
Mr Murphy was known to police and had previously been accused of possessing firearms and ammunition, and having the items in his possession for an act of terrorism for the UVF.
He was accused of blackmail and threats to kill last March and had been bailed after denying the charges.
