MURDER squad detectives hunting the killer of student Sara Cameron have released details of a vehicle, or possibly two, they would like to trace.

Finnish-born Sara's naked body was discovered in a field yards from her home in the North Tyneside village of Earsdon, near Whitley Bay, on Good Friday morning this year.

Sara, 23, was attacked as she made the five-minute walk along the A186 from the Shiremoor Metro station.

Police are trying to trace a car seen parked unattended in the cross hatched area of the A186, just before the start of the dual carriageway leading to the Earsdon roundabout, at about 7.30pm, on Thursday, April 20.

It was a dark-coloured older model Vauxhall Nova. At 11.30pm on the same evening, a Vauxhall Nova was seen parked at the Shiremoor Metro station.

It was mid blue and showing signs of rust, particularly at the bottom of the driver's door.

Detective Chief Inspector Ian Stephenson said last night: "These may be two separate vehicles or it may be one and the same car. Either way we need to trace the owner or owners."

Meanwhile, more than 800 men have been swabbed for DNA samples, and 320 have been eliminated from inquiries.
