A man and a woman remain in custody in Northern Ireland for questioning about the abduction and murder of Paul Crymble.
The father of two (35) was attacked by four masked men who confronted him and his wife when they returned to their home in Richhill, Co Armagh, early on Sunday.
The couple were tied up as the gang members, one armed with a gun, demanded money. Mr Crymble was then bundled into the family car, a green Seat Ibiza, and driven from his Ballybreagh Road bungalow.
His body was later spotted by a member of the public inside the vehicle parked at a lay-by two miles away. Police have said there was nothing to suggest a paramilitary or sectarian link to the killing.
