Officers investigating the murder of Rothienorman pensioner Brian McKandie say they have had an "encouraging" response to a nationwide TV appeal on Crimewatch.
Detective Chief Inspector Iain Smith made another bid for information on BBC1 last night (Monday September 26) for anyone with information about the 67-year-old's brutal death at his remote home at Fairview Cottages, Badenscoth, on Friday, March 11 to make contact with the show, Crimestoppers or the Police.
Brian's brother, Bill, also made an emotional appeal for information to find answers about what happened to the handyman.
He said: "We just can't put our finger on the reason for it happening - there seems to be no apparent reason.
"Somebody, somewhere knows what happened… It's easier to come forward and tell the police or you've got to keep that secret forever."
Following last night's appeal, a number of calls were received which officers say have given them "a number of lines of enquiry" to follow.
DCI Smith said: "I can only hope that the programme will encourage people to come forward to assist us in determining the full circumstances of Brian's death, and I would like to thank those who have made contact already.
"A dedicated team is investigating this incident with the assistance of a number of specialist officers and departments, however we are relying on information from the public.
"As our investigation continues into Brian's death it is crucial we build a picture of his life and acquaintances. If you are aware of anyone who would have been in his company, or know of anyone who was in contact with him, please let us know and we can quickly check as to whether we have spoken to them.
"I would also take this opportunity to once again remind the public for information about a boxy red or burgundy coloured estate car seen at Brian's address on Friday March 11, 2016. Following extensive enquires the timeframe for the various witnesses seeing this car has been narrowed to between 1.30pm and 2pm, and the persons seen at Brian's address at that time are broadly described as -
1 - An older male, possibly 40-50 years old, of a heavy build with dark hair
2 - A younger male, possibly 20-30 years old, of a thin build with blonde hair, possibly collar length
"Although sometimes described as a Volvo style estate car, it could be any old estate car of similar shape and features. This car has not yet been traced yet and these people have not yet come forward."
If you think you have any information that could assist please contact Police on 101. If you would prefer to remain anonymous please contact Crimestoppers on 0800 555111. The charity has offered up to £10,000 reward for information that can lead to conviction.
