Malcolm McKeown murder: Two men arrested over shooting
Two men have been arrested on suspicion of the murder of Malcolm McKeown.
The 54-year-old was found dead in his silver BMW behind Dewart's service station in Waringstown, County Down, on Monday night.
The men, aged 24 and 25, were arrested on Saturday morning and were taken to Musgrave serious crime suite where they remain in police custody.
Det Ch Insp Peter Montgomery said he was keen to trace the driver and passengers of a Volkswagen Passat.
The dark blue or black car has the registration plate RK62 PLX, and was found burnt out in Glenavon Lane in Lurgan shortly after the murder.
"I believe the gunman or men may have got out of this car, walked around the back of Dewart's to shoot Malcolm McKeown, before fleeing and leaving Cambrai Heights in the car at 19:20 BST," he said.
"CCTV footage shows Mr McKeown entering the shop at Dewart's Garage at approximately 19:15 BST on Monday and then walking back to his car approximately four minutes later.
"It was around this time I believe that the gunman or gunmen shot him."
The father-of-three's body was found by two teenage boys at 21:00 BST.
Det Ch Insp Montgomery appealed for more information, and asked for the public's help on whether or not the occupants of the car got into a dark coloured Jeep or made off on foot.
Police said Mr McKeown had been shot up to six times at close range and had bullet wounds to his head and body.
A 30-year-old man and a 28-year-old man arrested by detectives on Wednesday were released unconditionally.
