POLICE are still calling on the public for more information about the murder of Shandee Blackburn.
The woman in the CCTV footage has come forward and provided information to Mackay Police but they are still urging the community to come forward about the second piece of information.
It is believed that one person has shared the CCTV footage of the white car on Facebook and another person has commented on it. Police are wanting to speak to the person who gave very specific details on that shared post.
Watch the video below:
POLICE are calling on the public for more information on murdered Mackay woman Shandee Blackburn.
Crime and Support Services Detective Inspector Karyn Murphy said police had received a number of phone calls regarding footage of a vehicle of interest released earlier this year.
"There is one caller in particular we'd like to recontact us, that caller contacted CrimeStoppers and stated they had seen that vehicle at the Girl Guide Hut at Juliet Street on the night in question," she said.
"We've obviously got some more questions for that caller if they could please contact CrimeStoppers or Mackay police."
Police are also appealing for another potential witness to come forward who may be able to help with the investigation.
"We released footage of a female person in a small black vehicle, this person was at (United) service station at about midnight on that night, we haven't been able to identify that person at this point," Det Insp Murphy said.
"If it is you or you know that person could you please contact us."
Ms Blackburn was found murdered on Boddington Street in the city on February 9 last year.
Anyone with information is urged to contact Crime Stoppers on 1800 333 000.
