Officers investigating the murder of 25-year old Joanna Yeates in Bristol have said that there is no evidence of sexual assault but cannot rule out a sexual motivation behind the killing.
BBC News has reported that police investigating the death of the landscape architect say that Jo Yeates was not subjected to a sexual assault.
Detective Chief Inspector Phil Jones said today in a press conference that he was satisfied that Jo Yeates had arrived home safely on the night of December 17. He wouldn't speculate on the chain of events that followed or the circumstances surrounding the murder. He said, "I am satisfied that Jo got back to her flat but I am not going to speculate whether she let someone into the flat, whether someone was already there or whether someone broke into the flat. These are all lines of enquiry which my team are pursuing. At this time I am cannot say where or when Jo was killed or when her body was left on Longwood Lane."
He also made an appeal for information on a light coloured 4x4 vehicle. Sightings of this vehicle have been reported by people contacting police with information. DCI Jones urged the people in that car to come forward. He also urged anyone who was in the area where Jo's body was found to come forward.
He also reiterated that the missing pizza and the cider that Jo bought on the night of her disappearance was still of importance. He said, "Details surrounding the pizza and the cider are all relevant and I appreciate have been of ongoing interest. What I can tell you is that we still haven't found the pizza, but we have searched all bins in the area and we are working through 293 tonnes of domestic rubbish seized in the vicinity. This is a demonstration of the level of detail we are pursuing on this enquiry.
"At this stage it is still not absolutely clear whether Jo had eaten the pizza. We continue to work with experts to determine this."
He also thanked members of the public for their continued response to the appeals for information. The force has received over 1300 pieces of information via email, phone and direct contact with police officers. The investigation team has been able to use this to put together over 900 lines of enquiry and has prioritised 239 as high priority.
DCI Jones pointed out that over 100 hour of CCTV footage had already been viewed by officers.
At the press conference he asked people to continue to contact them with information, no matter how insignificant they felt it might be. He said, "I cannot stress enough the fact that every single piece of information is important. You may feel it is not significant or that we may already know, but please call the Operation Braid incident room on 0845 456 7000 and let us make that decision."
BBC News said that DCI Jones was questioned about the arrest last week of 65-year old Chris Jefferies, Jo Yeates landlord. DCI Jones replied, "The arrest which was made and the search of the premises were made at the appropriate time and as soon as possible."
He also said that forensic examinations at the flats in Canynge Road would continue until later in the week.
