Police are searching for a 26-year-old man after his newlywed wife was found strangled.
Vicky Roberts' body was discovered dumped in a garage at their home in Runcorn, Cheshire on Thursday.
Officers were called to the block of apartments after being contacted by the 25-year-old's father, who was worried he had not heard from his daughter.
Detectives released a wedding day photo of the couple, who married six months ago, while renewing their appeal for her husband Michael to come forward.
A Cheshire Police spokeswoman said: "Her death is being treated as suspicious, and a post-mortem to determine the cause of death took place yesterday.
"Early indications are that the cause of death was strangulation, although further tests will need to be carried out."
The couple's home has been sealed off for forensic examinations.
One neighbour said: "Michael and Vicky had lived upstairs for about a year.
"Mike was in our house for half an hour yesterday before it all happened."
Roberts' family declined to comment at their home in Warrington.
Detective Inspector Andrew Smith of Cheshire Police said: "I would ask Michael, if he hears this appeal, to make contact with police so that we can speak with him.
"It is several days since Victoria's body was found and you have not made contact with your family, who are now very concerned regarding your well being.
"You can contact any police station and speak with any police officer, or directly contact myself and my team on 0845 458 0000. It is important that we speak with you."
