Police and sniffer dogs rushed to Cramlington earlier today following reports a wanted man had been spotted there.
Officers were seen at Northumbria Specialist Emergency Care hospital at around 11am, and it is believed they were looking for North East man Alexander Carr.
She had suffered stab wounds to her neck.
Carr, who is from Sunderland, has links to London and Northumberland, and is also known to visit Newcastle and North Tyneside.
A search of the grounds was carried out, but it is now believed Carr was not present at the site.
A Northumbria Police spokesperson said: “Today [Thursday] officers attended Cramlington Hospital following information received concerning a wanted suspect.
“The suspect was not present, and enquiries are ongoing to locate him.”
The 32-year-old is thought to be actively evading arrest.
To help with the search, Crimestoppers has issued a £10,000 reward for any information submitted exclusively to it which leads to Carr’s arrest.
Members of the public should not approach him, but instead alert officers immediately if they have seen him or know of his whereabouts.
