We are now treating this investigation as a murder inquiry.
I want to ask that anyone who knows what happened last night, or who has any information on this incident to get in touch.
We have a lot of officers out in Aylesbury today conducting house-to-house enquiries and I want to reassure the community that we are doing everything to catch this offender.
We do not currently believe this was a random incident, but I urge anyone with information to contact police immediately.”
