The Daily Mail has pieced together the steps towards radicalisation:
Over the next two decades the burly bodybuilder was convicted of a catalog of offences including assaults, grievous bodily harm, possession of weapons and public order offences, and was jailed twice.
He drifted from job to job, working as a sales rep and running a television aerial installation business, before meeting his long-term partner Jane Harvey, 48, a successful businesswoman, in 1991.
He then moved into her £700,000 gated home in the village of Northiam, near Rye in East Sussex.
Glorious stuff. After a crime is committed, the press usually say "the police are calling for witnesses", they should add on "… and the Daily Mail are calling for any house price info related to the case, however tangentially".
