Joanna Yeates was strangled by a neighbour who drove to a supermarket minutes later with her body in the boot of his car, then texted his girlfriend to say that he was bored, a court heard yesterday.
CCTV footage played to jurors showed Vincent Tabak, 33, at a store in Bedminster, Bristol. He bought crisps, rock salt and beer before dumping the 25-year-old landscape architect's corpse in a country lane, jurors were told on the first day of his murder trial.
Yeates disappeared just before Christmas last year. As her family waited for news, Tabak was using the internet to research the rate at which a body decomposes, Nigel Lickley, QC, for the prosecution alleged.
Tabak, 33, a Dutch engineer, went on with his normal life "misleading and manipulating" everyone around him, Lickley said.
After a week-long search, Yeates' body was found covered by snow at Failand, near Bristol, by a couple walking their dog. Tabak, who admits manslaughter but denies murder, listened with his head in his hands.
