Officers investigating the murder of Rothienorman pensioner Brian McKandie have launched a fresh appeal to urge his customers to make contact as investigations continue.
People living in the North East including local businesses, community groups and centres are being asked to share a new poster urging anyone who was in contact with the 67-year-old before his death to come forward.
Local policing teams will be issuing posters where possible, however copies will also be available to pick up from local police offices.
Detective Chief Inspector Iain Smith said: "An extensive forensic examination of Brian's address has resulted in the recovery of forensic evidence and we are keen to identify anyone who knew Brian, was a customer of his or frequented his address for any reason to let us know.
"Despite repeated appeals and being more than six months on we are still identifying new customers all the time. I would urge you to think back - have you ever been a customer of Brian, or do you know of anyone who was who might not yet have come forward?
"You may think your information is not important however I would respectfully ask you to let us make that judgment. It could well be of great assistance.
"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."
