Margaret Muller, 27, was stabbed to death as she jogged in Victoria Park, Hackney, on 3 February this year.

Her body has been taken back to the US by her family and the funeral will take place in Charlottesville, Virginia.

Police investigating the case held London's largest crime reconstruction on 3 March, a month to the day of the murder.

Some 93 people returned to the scene to retrace their steps while 100 officers and 100 support staff helped map their positions.

Since then two men have been arrested.
