A shocking photograph showing the blood-splattered doorway where TV presenter Jill Dando was gunned down 20 years ago has been released.
Crimewatch presenter Jill, 37, was shot once in the head on her doorstep in Fulham, London on April 26, 1999.
The horrific photo, aired on the BBC's The Murder of Jill Dando, shows blood splattered on the door, with a trail over the path leading up to the house.
Random items are strewn around the scene and, most chillingly, her handbag sits by the foot of the door.

ShareThe BBC documentary shown last night featured interviews with her family and some of the senior police officers involved in the investigation.
Presenter Jill Dando (pictured above outside her home in Fulham) was murdered in 1999
It heard from neighbour on Gowan Avenue who first discovered her body and played the harrowing 999 call made to police.
Helen Doble can be heard sobbing after coming across Jill's body just monents after she was shot dead.
As she struggles to stay calm she says: 'I'm walking along Gowan Avenue.
'It looks like there is somebody collapsed... Confidentially it looks like it's Jill Dando and she's collapsed.
'There's a lot of blood.'
The operator asks her calmly: 'Can you just approach and check that the lady's breathing for me.'
Miss Doble replies: 'She doesn't look as though she's breathing. She's got blood coming from her nose. Her arms are blue.'
The operator tells her: 'I just need to find out if she's breathing. Is the lady's chest going up and down?'
Sobbing and breaking down Miss Doble says: 'Oh my God, no, I don't think she's alive. I'm sorry.'
Detective Chief Inspector Hamish Campbell, from the Metropolitan Police, who investigated the killing and helped convict George was also interviewed.
He told the documentary: 'Sometimes I felt we were a day away from solving it and other times, I thought "no, we're a long way away".
'Senior officers were asking "what are the likelihoods of this case being resolved?"
'We had over 2,000 people named as potential suspects or responsible. Some actions to trace and eliminate one person might take a day. One action might take two weeks.
'But there's thousands of them and that's the issue of managing stranger homicides.'

The new documentary revealed the decision-making happening behind the scenes of the inquiry into Miss Dando's murder.
It showed how a particle of gunshot residue in the pocket of a coat police found in Barry George's house became the key forensic evidence against him.
The gunshot residue evidence was discredited at George‘s 2007 appeal, when his murder conviction was quashed. It was deemed inadmissible as evidence at his 2008 retrial, when he was cleared.
Miss Dando’s family still remain ‘hopeful’ her killer will be brought to justice one day.

Speaking during the documentary, her brother Nigel Dando, 66, said: 'I would like to see somebody charged and convicted, but I would just like to know why someone would want to kill her.
'I would like somebody, the person who did it, to be able to tell me, or to be able to tell a jury or a judge, why it happened.
'And that would be fine, that would put my mind at rest and that would be the closer for me. It's unlikely but I remain hopeful.'
The film also showed how BBC director general Tony Hall, then Head of News at the BBC, was targeted with threatening phone calls in the weeks after Jill Dando's murder.
'We had three calls, as I recall, to the BBC switchboards in London and Belfast,' he said.

'I listened to the voice of one of them, which said basically, I was next. I mean they were threatening me. I have no idea what that amounted to, Was it a real threat? Was it not a threat?
'You know there are often copycat things that happen after these sorts of events, and the police took it seriously, but I don't know.'
And it explored some of the theories behind the killing as detectives struggled to find a motive.
Six distinctive marks were found on the cartridge case (pictured above) used by the gunman who killed Jill Dando
One was the Serbian hitman theroy, that she was killed in retaliation for her work covering the Kosovo war and the Nato bombing of Serb journalists.
The TV presenter's cousin Judith Dando was also interviewed, saying: 'She wasn't too good to be true, this is really who Jill was.
'She didn't have any enemies, it's so ridiculous. 'Why would they…why would they target Jill?
'What possible reason could anyone have for doing that, except, of course, the fact that she was in the public eye?'
