Were two people involved in the Joanna Yeates murder?

British police are investigating the possibility that more than one person might have been involved in the murder of Joanna Yeates, reports suggest.

BRITISH POLICE INVESTIGATING the murder of Joanna Yeates are exploring the possibility that more than one person might have been involved in her murder, reports suggest.

There is no evidence to suggest that the 25-year-old landscape architect was sexually assaulted, police said in a press conference yesterday.

Detective Chief Inspector Phil Jones of Avon and Somerset Police said:

At this stage there is no evidence to suggest that Joanna was sexually assaulted. However, I have not ruled out that there might have been a sexual motive.

He fuelled speculation that there may have been more than one person involved when he added:

I can assure you, we are determined to solve this crime, and bring Jo’s killers to justice…I think that phrase emphasises that I am not making any assumptions in this case.

Detectives have appealed for help in tracing a light coloured 4×4 that was seen near the spot where her snow-covered body was discovered on Christmas Day.

Her landlord, ex-teacher Chris Jefferies, 65, is still a suspect, despite being freed on bail.
