Buro Happold consultant will spend a minimum of 20 years in jail.
Buro Happold consultant Vincent Tabak has been convicted of the murder of Joanna Yates at Bristol Crown Court.
Tabak had pleaded guilty to the manslaughter of Yates, a BDP architect, but had denied murder.
He was sentenced to a minimum of 20 years in jail.
Yeates and Tabak lived next to one another in the Clifton area of Bristol, where Yeates was heading home to on the 17 December, the night she disappeared.
Her body was found in Longwood Lane, Failand, by dogwalkers eight days later.
A post-mortem found that she had been strangled.
Tabak was remanded in custody and will face trial at Bristol Crown Court.
