A woman found dead in a Birmingham country park was strangled, it has been revealed.
West Midlands Police said detectives have launched a murder inquiry following a post-mortem examination.
But, more than 48 hours after the grim discovery was made by a dog walker, officers were still no closer to finding out who she was.
All that was known about her was that she was white, probably in her 30s and had auburn shoulder-length hair, was 6ft tall and had a tattoo on her hand.
The woman had no forms of identification and was not wearing any jewellery when she was found in a brook at Sheldon Country Park. She is thought to have lain there less than one day
A force spokesman said: “The death is certainly being treated as suspicious and it will be a murder investigation. The key thing now is to identify this woman.”
Police said they were concerned no-one had yet reported as missing anyone matching her description.
Checks on missing persons records had also failed to provide a breakthrough in her identity. The area was sealed off throughout the weekend after the woman’s body was discovered at 12.45pm on Saturday.
A blue police tent could be seen among the trees close to the spot where the corpse was found while police carried out a search for evidence.
It was not clear whether the spot was where she met her death or whether her body may have been carried along the stream by the water.
While the spot is secluded, it is regularly used by dog walkers so it was thought the woman’s body would have been there for less than two days.
Police appealed for members of the public with neighbours or relatives matching the woman’s description to come forward.
She was wearing a black parka-style jacket, blue jeans and black zip up ankle length boots with a silver buckle.
