A couple who were found dead in their home, leaving their two-year-old daughter an orphan, have been named by police.
Margaride Rufino, known as Guida, 38, and Anthony Roberts, 37, were discovered with fatal injuries at a house in Idle, Bradford, on Sunday.
West Yorkshire Police confirmed they have launched a murder investigation and are not looking for anyone else in connection with the deaths.
Police said the couple's two-year-old daughter was not in the house at the time of the attacks and is now being cared for by family members.
Detective Chief Inspector Ian Scott said: "The police investigation is still at an early stage; however, we are treating this as a murder inquiry.
"A full post-mortem will be conducted to determine the cause of death for both Ms Rufino and Mr Roberts.
"At this stage we are satisfied that no other parties were involved in the incident."
Police were called to a "domestic incident" on Sunday evening and found Ms Rufino with serious injuries to her neck and Mr Roberts with serious injuries to his leg.
Both were pronounced dead at the scene and two knives were recovered from the house.
West Yorkshire Police are appealing for anyone who heard or saw any suspicious activity in the area at around 6pm on Sunday to contact the Homicide and Major Enquiries Team on 101, or Crimestoppers, anonymously, on 0800 555 111.
