On the night Alistair Wilson was shot, a CCTV camera was pointing straight at the family home.
But mysteriously, the system malfunctioned and no useful footage was retrieved from the device just 50 yards from Crescent Road.
While the camera was working, recording equipment at Nairn police station failed to preserve the pictures.
There were three CCTV cameras in the immediate area of the Wilson home – one outside the Havelock Hotel, almost opposite the house, and another on the wall of a housing complex in Marine Road.
The third was mounted high on the wall of the Free Church in Academy Street, which faces Crescent Road.
At the time, the town’s CCTV system had undergone recent improvements as part of a £200,000 upgrade to the Highlands’ security network.
But that was not the only technical failure that night.
The 999 call made by Mrs Wilson at 7.11pm was also lost because the ambulance service’s digital system – designed to record all calls – crashed.
The fault happened at 7pm, just minutes before the killing, and the system was out of action for four hours.
