Police investigating the death of GMP detective Leanne McKie have appealed for the public’s help to establish her movements before her body was found in a lake.
An image of the mother-of-three’s car - a red Mini Countryman, registration DA12 DFO - has been issued.
Murder squad detectives said they need to know more about her movements in the vehicle and have issued a plea for information.
Ms McKie, 39, from Wilmslow, worked as a detective constable in GMP’s serious sexual offences unit.
Her body was found in a lake at Poynton Park, off London Road North in Poynton, near Stockport, in the early hours of Friday morning.
A murder investigation has been launched and a 43-year-old man has been arrested on suspicion of murder.
Cheshire Police said in an update on Sunday night that he remained in police custody, assisting officers with their enquiries.
Det Insp Adam Waller appealed for anyone who saw the Mini during the afternoon of Thursday, September 28, into the early hours of Friday, September 29.
He said: “This is an ongoing investigation and we are working hard to establish the full circumstances surrounding the incident.
“As part of our ongoing enquiries I’m appealing for information from the public to help establish Leanne’s movements in the hours leading up to her death.
“I’m keen to hear from anyone who believes that they may have seen Leanne’s red Mini, registration number DA12 DFO.
“I’d like to hear from anyone with any information, and particularly anyone with any dashcam footage, that may have been driving along, or in the immediate vicinity, of the A523 between Poynton and Poynton Park or along the A5149 Chester Road, towards Wilmslow, between the hours of 11.30pm on September 28 and 3.30am on September 29.”
He also appealed to anyone in the vicinity of Poynton Park with information to come forward.
The Mini has been recovered and is being examined.
GMP Chief Constable Ian Hopkins said Ms McKie joined the force in 2001.
In a tribute he said: “My heart particularly goes out to her three young children, who she adored. Leanne worked tirelessly to provide support and seek justice for victims of sexual crimes.”
Police were first called at around 3.45am on Friday to reports a body had been found in the lake at Poynton Park.
