Officers investigating the murder of Brian McKandie in Rothienorman spoke to people in more than 700 vehicles as part of enquiries two weeks on from when he was attacked.
Police stopped motorists in the Rothienorman area on Friday, 25 March, exactly two weeks on from when officers believe Mr McKandie was murdered.
Mr McKandie was attacked and died at his home on Friday 11 or Saturday 12 March 2016. He was found on Saturday, 12 March at his home at Fairview Cottages, Badenscoth, Rothienorman.
Detective Chief Inspector Iain Smith said:
"It is now just over two weeks since when we understand Mr McKandie was attacked and officers spent much of last Friday speaking to people travelling in the area. Information was received from a number of people in terms of assisting us with our enquiries to identify people who may have been in contact with him before he died.
"This gives us potential fresh lines of enquiry to follow. We are still appealing for two sets of men who may have visited him on the Friday (11 March) to come forward as this may assist us.
"We have also requested that if anyone was driving on the B9001 between Rothienorman and Forgue at any point on Friday 11 March 2016 who was using their dashboard camera, I would ask them to copy the footage from that part of their journey, especially as they were driving through Badenscoth, save it to disk and hand it into their nearest police office.
"The information within the footage will potentially help us progress the enquiry forward."Police can be contacted on 101."
