Margaret Sheehy, known as Margot, was found strangled to death on the afternoon of June 12, 2012.

Her eldest son, Mr Heiss, has been extradited from Spain to face a charge of murder, which he denies.

Jurors have been told he admits the killing, but will claim diminished responsibility.

Detective Constable Murray Bannister led the jury through an hour-long CCTV compilation on Friday. The video was pieced together using the timing of bank card transactions.

His first stop was the McCluskey's newsagent in Bloomfield Road, near Ms Sheehy's flat, where he first used her bank cards to buy Rizla papers at about 7pm on June 11.

He is next seen walking past Pizza Express in St Mark's Hill, Surbiton, carrying a holdall, at 2.23am the following morning.

From there he visited ATMs at Barclays and Halifax in Victoria Road, withdrawing a total of £200.

Mr Heiss then boarded an N65 bus outside Waitrose in Claremont Road, which he rode to Richmond.

After finding Richmond station closed, he boarded an N33 bus towards Hammersmith at 3.32am. From there, he got on an N9 bus towards Heathrow, where he arrived at 4.45am.

He entered the Tube just after 5am, and arrived at St Pancras International at 7.48am.

After buying his ticket and passing through security screenings he boarded a train to Paris shortly after 9am.

The trial continues.
