Tests on a British student murdered in Italy revealed evidence of sexual activity shortly before her death.
Meredith Kercher was a student in Perugia, Italy
But the coroner did not confirm if Meredith Kercher, 21, who was found dead in the bedroom of her Perugia flat on Friday morning had been raped.
Miss Kercher, from Coulsdon, south London, is thought to have been stabbed with a pocket knife.
Her partially-clothed body was found under a duvet at the house, close to the city centre.
Let killer inside
Reports showed her body showed signs of bruising.
Miss Kercher is known to have gone to at least one party on Halloween, the night before she died, leading police to believe she may have known her killer and even met him at the party.
The next evening, Thursday, she had dinner with a female friend, and went home in the middle of the evening.
One theory is that she opened the door of the house and let the killer inside.
Officers have been carrying out checks for fingerprints on two mobile phones belonging to Miss Kercher, which were found at or near the scene.
An elderly woman found one mobile abandoned in her garden and handed it in to the police.
They then traced it to the flat where they kicked in the door and discovered Miss Kercher's body.
In a statement, Miss Kercher's family said: "Words cannot even begin to describe how we feel right now, other than utterly devastated at the tragic loss of our daughter and sister Meredith."
The family thanked friends and colleagues for their support and "sheer volume of tributes" which had "poured" in for the daughter who they described as someone who "worked hard" and was "the most beautiful, intelligent, witty" person.
Appealing for information to help find Meredith's killer the statement concluded: "We loved her then, we love her still and she is still very much a part of our family forever."
Miss Kercher's father was expected to attend a candlelit vigil in her memory in Perugia on Monday at 2100 BST.
