Det Chief Insp Mark Oughton said Alena’s naked body was ‘well concealed’ when it was found in a dried stream bed behind the Fitzwilliam Arms pub, Parkgate, Rotherham, a week ago.
The 38-year-old, originally from Slovakia, had last been seen just outside the pub on Taylors Lane on Boxing Day 2018.
The detective said Alena – a mum-of-four – was wearing a distinctive black sweater with the words ‘little black sweat’ on them, black bottoms with white stripes down the side, black flip flops and hair extensions – all of which he said had been dumped in the area and were still ‘outstanding’.
Det Chief Insp Mark Oughton said: “I do believe answers around what happened to Alena lie within the local community and I’d encourage people to keep speaking to us, if they have any information or concerns.
“Did you see Alena on Boxing Day 2018 in the Parkgate area? She was last seen leaving the Fitzwilliam Arms Hotel on Taylors Lane at 10.30pm that evening, walking towards Rawmarsh Hill.
“Earlier that evening, at around 8.30pm, she was seen with a man on Scrooby Lane, walking towards Mangham Road, was that you? Were you with Alena that evening?
“Have you seen Alena’s clothing? It may have been discarded in the local area. She was last seen wearing a thin black sweatshirt with ‘Little Black Sweat’ written on it in white, black tracksuit bottoms with white stripes down the side and black sliders.
“She was also wearing blonde clip-in hair extensions. These items have not been recovered and remain outstanding.”
DCI Oughton again refused to reveal how the body had been concealed but added he believed it had been there since ‘late December’.
He said the area was searched when Alena was first reported missing in January, a review was then carried out, and it was searched again last week.
Officers remained at the scene on Friday, searching for evidence and Alena’s clothing.
DCI Oughton added: “Between Boxing Day 2018 and Monday 8 April 2019, have you seen anything unusual or anyone acting suspiciously in the area?
“Any information, no matter how small, could prove to be incredibly helpful. Please do not hesitate to contact us if you think you can help.”
A 45-year-old man, arrested on suspicion of Alena’s murder has been bailed pending further enquiries.
Anyone with any information should call police on 101, quoting incident number 453 of April 8 or call the incident room on 01709 443540.
