Police say they believe a man wanted in connection with the murder of Linzi Ashton, 25, is still somewhere in Salford.
Officers have appealed for help in tracking down Michael Cope, 28, after the young woman was found dead at her home on Saturday.
"We know that he has previously been in a relationship with Linzi and through that relationship there have been reports to police in respect of allegations made by her," said Detective Chief Superintendent Darren Shenton.
"The purpose of today's appeal, and what should very much be the focus, is our need to arrest Michael Cope and we are appealing for the public to assist us with this.
"If anyone has seen him or knows where he is it is absolutely vital you contact the police."
Michael Cope, 28, has been named by police they want to speak to in connection with the murder of mother-of -two Linzi Ashton, 25, whose body was discovered after police were called to a house in Westbourne Road, in Winton, Salford, shortly before 6pm yesterday.
Police said the man they have named that they want to speak to over the "brutal" murder of a mother-of-two at her home, had been in an "acrimonious" relationship with her.
Michael Cope, 28, had a turbulent love life with Linzi Ashton, 25, and had been the subject of previous police contact, Greater Manchester Police said.
Detective Chief Superintendent Darren Shenton said:
It is an early stage of the investigation and I am not going to speculate as to to the cause of Linzi's death. However, I am satisfied that she has been brutally assaulted.
Michael Cope and Linzi had been in a relationship. That relationship has been acrimonious and indeed the subject of reports to the police.
A young woman has been brutally murdered. I believe the person responsible is this local man Michael Cope and I need the public's support to locate and actually provide information which will allow the police to arrest Cope.
Cope himself can surrender to the police and contact any local police officer or police station but I give this caveat to people who may know Cope and may be harbouring him - I would take a particular dim view of anybody who provides assistance to Cope knowing that he is being actively searched by police in connection with this murder.
Police have appealed for more information after the body of a woman was found in her home.
Linzi Ashton, 25, was discovered after police were called to a house in Westbourne Road, in Winton, Salford, shortly before 6pm yesterday.
Detective Chief Superintendent Darren Shenton from Greater Manchester Police said:
A young woman has been murdered and our thoughts are with her family and friends at what is obviously a totally devastating time for them.
While it would not be appropriate for us to comment on how she died at this time, a full and thorough post-mortem examination will be taking place in due course to establish exactly how and when she died and following that we will be in a better position to provide more information.
I want to reassure her loved ones as well as those in the local community that we have a team of highly skilled detectives already working on this case but if anyone has any information they think can assist please call us.
Anyone with information should call police on 101, or Crimestoppers, anonymously, on 0800 555 111.
