Jill Dando and Nicholas Witchell presenting Breakfast News in 1989
When BBC presenter Jill Dando was shot dead on the doorstep of her home in London nine years ago, the Metropolitan Police launched its biggest murder inquiry to find her killer.
This is how the story unfolded.
26 April 1999 Jill Dando, 37, is shot dead with a single bullet to the head at point blank range outside her home in Fulham in south west London.
She had been returning from her fiancé Alan Farthing's house in Chiswick.

26 February 2001 The trial of Barry George begins. He denies murder.
