The death of Libby Squire is now being investigated as a potential murder after her body was recovered from the Humber Estuary near Grimsby Docks.
As previously reported, the body of the 21-year-old was recovered from the water close to Spurn Point at around 3.30pm on Wednesday, March 20.
A post-mortem examination was carried out before a formal identification took place.
A man was previously arrested in connection with Libby’s disappearance and remains under investigation. Libby was last seen just after midnight on Friday, February 1.
Humberside Police said throughout the missing person enquiry it was considered that Libby may have come to some harm. The force is now solely investigating it as a potential homicide.
The University of Hull has created a space for tributes to Libby, which is open to both students and the community to attend and leave messages of condolence.
Detective Superintendent Martin Smalley said: “Our thoughts remain today with Libby’s family and friends at this incredibly sad and devastating time for them.
“The loss of a loved one is always an upsetting and traumatic experience to go through, but the circumstances surrounding Libby’s death will only intensify the heartache for her family.
“Specially trained officers continue in supporting Libby’s family and we will do all we can to provide further support and assistance to them in any way we are able to.”
He added: “In regards to our investigation, while we have considered throughout the missing person inquiry that Libby may have come to some harm, Libby’s death and the recovery of her body now leads us to solely investigate as a potential homicide.
“The post-mortem examination concluded late last night and at this stage, we will not be releasing any results for investigative and operational reasons.
“We have to protect the integrity of the investigation, which is live and very much active and ongoing, with one man who remains under investigation.
“An inquest into Libby’s death will be opened on Monday afternoon (March 25) at Hull Coroner’s Court at 1pm.
“Libby captured the hearts of not just the people in Hull, but across the country, and as I have said before, the support shown has been overwhelming and my sincerest thanks to absolutely everyone who has been involved.”
