Jones' uncle Stuart Campbell, a builder, was convicted in December 2002 of abducting and murdering Jones (16 October 1985 - c.18 June 2001), and lost an appeal in January 2005.
Jones' body has never been recovered, and Campbell has always maintained his innocence. After the trial, controversy arose when it was revealed that Campbell had prior convictions for indecent assault on other girls of similar ages. The use of forensic authorship analysis of text messages in the case provoked research into its use in other cases.
Disappearance and investigation
Jones was last seen in East Tilbury, Essex, on 18 June 2001, while walking to a bus stop.
Suspicion fell on Campbell almost immediately who was first arrested on 23 June 2001, five days after Jones went missing. Detectives had delayed his arrest whilst weighing the possibility of endangering Jones' life, on the presumption that she was still alive, against the possibility of Campbell leading the police to her.
During police interviews Campbell was described as "uncooperative" In one 20 minute interview with the police Campbell refused to comment on 50 questions.
The investigation included several appeals to the public for information, including a reconstruction on the BBC television programme Crimewatch UK. During the investigation, over 900 police officers and support staff searched over 1500 locations for Jones' body.
Murder trial
The police who investigated Jones' disappearance were convinced within two months of her disappearance that she had been murdered. A police superintendent said to the BBC that Campbell "developed a relationship with Danielle that was certainly inappropriate and probably unlawful." Jones apparently tried to disengage, but Campbell resisted.
By 14 November 2001 the Crown Prosecution Service decided that the police had enough evidence to prosecute Campbell for murder even though it would be harder to secure a conviction without a body.
In October 2002, Campbell went on trial for abduction and murder. The trial was unusual in the UK as prosecutions for murder without a body are rare. The Crown's case rested upon several pieces of evidence.
Jones had disappeared without contacting her parents and had been seen talking to a man in a blue Ford Transit van resembling Campbell's on the morning of her disappearance. The testing of blood-stained stockings had found Jones' DNA and Campbell's DNA on the stockings, lip gloss used by Jones was also found in Campbell's home.
A diary kept by Campbell revealed an obsession with teenage girls, with testimonies that Campbell had manipulated young girls into posing for topless photographs. Mobile Switching Center records demonstrated that Campbell's alibi of being at a D-I-Y store half an hour away in Rayleigh was false, and that Campbell's and Jones' mobile phones had been within the range of a single mobile phone mast at the time that a text message had been purportedly sent by Jones to Campbell.
This along with forensic authorship analysis indicated that Campbell had written the message, not Jones, implying that Campbell had sent the message to himself using Jones' phone to make it appear that she was still alive.
Campbell was found guilty of both charges on 19 December 2002 and sentenced to life imprisonment for murder to run concurrently with a 10-year sentence for abduction. No recommended minimum term was reported at the trial, and there have been no reports since as to whether the High Court has decided upon Campbell's minimum sentence.
The use of text messaging evidence in the trial inspired a group of researchers at the University of Leicester to begin studying text messaging styles, in the belief that research into the forensic authorship analysis of such things would help with further criminal cases.
In 2004, Campbell was granted leave to appeal his conviction, on the grounds that evidence of his obsession with Jones and of his interest in schoolgirls should have been excluded at his trial and on the grounds that one of the jurors should have been discharged because they were the next door neighbour of a police officer involved in the case. The appeal was dismissed In 2005 by the Court of Appeal.
On 28 July 2005, an inquest by the coroner was held into Jones' disappearance, returning a verdict of unlawful killing. Interim, police interviews with Campbell in prison, regarding the location of Jones' body, reported that Campbell had not had anything to say regarding the location of Jones' body.
Other cases
Contrast between this case and the murder of Hannah Williams have been drawn, citing the disparity in news media coverage of the two as an example of missing white woman syndrome.
Jewkes cites the media coverage of the Jones case as an example of the news media's eroticization of the victim in such cases, pointing to the news media's reports of the "inappropriate" (i.e. abusive) sexual relationship between victim and murderer, and the news media's publication of photographs of the victim's stockings.

For years, Stuart Campbell hid his secret from other members of the family.
He was fascinated by teenage girls, and eventually his interest turned to his 15-year-old niece, Danielle.
She had no reason to fear the man she knew only as her uncle, a trusted member of the family.
But in reality he was a sexual predator, prepared to betray that trust and take her life.
"He developed a relationship with Danielle that was certainly inappropriate and probably unlawful," says Detective Superintendent Peter Coltman.
"She apparently tried to disengage herself, but he resisted."
Danielle was last seen near her home in East Tilbury, on her way to catch the bus she took to school.
She was seen with a man who drove a blue van. Stuart Campbell, a builder, had just such a vehicle and quickly became the focus of police attention.
At that stage, however, there was nothing else to connect him with Danielle's disappearance.
Detectives faced a dilemma. They could arrest the builder and bring him in for questioning. Or they could wait and watch, in the hope he would lead them to Danielle.
"In the context of a belief that Danielle was still alive, and being held against her will, this was an extremely difficult decision," recalls Mr Coltman.
"Would such action locate Danielle, or could it put her life in danger?"
White stockings
He decided to arrest Campbell, but any hopes that this would result in Danielle being reunited with her parents were quickly dashed.
When they searched his house, detectives found a canvas bag in the loft.
It contained a pair of white stockings, stained with blood. DNA tests showed a match for both Danielle and Campbell.
There was also a diary detailing his contact with the girl, camera equipment, and material of a paedophile nature.
Even without a body, police were by now in little doubt that they were dealing with a case of abduction and murder.
Danielle's parents, who had been clinging to the hope their daughter was alive, had to face the fact that she had been killed by her uncle.
As the search for Danielle's body continued, detectives were learning more about Campbell's interest in teenage girls.
He used to approach them in the street, posing as a photographer, and invite them into his home.
It emerged after the trial that Campbell was given a 12-month suspended sentence jail term in 1989 after holding a 14-year-old girl at his home and photographing her in a karate suit.
He had originally been charged with abducting the girl and taking indecent pictures of her - that charge was dropped after he admitted to taking a child without lawful authority.
In 1976 he was given a four-year jail term after being convicted of robbing a 16-year-old girl in the street.
Campbell continued to insist he knew nothing of Danielle's disappearance, but his devious nature proved to be his undoing.
Text message
He said that on the morning Danielle disappeared he was miles away at a DIY store in Rayleigh. But his mobile phone showed this to be a lie.
He then claimed that Danielle had sent him a text message after she disappeared, saying she was in trouble at home. The message read:
"HI STU THANKZ 4 BEIN SO NICE UR THE BEST UNCLE EVER! TELL MUM I'M SO SORRY LUVYA LOADZ DAN XXX"
But Danielle used to write her messages in lower case letters, and this message was all in capitals.
Detectives were convinced Campbell had sent the text message to himself...and to do that, he must have had Danielle's phone.
The sequence of events that led up to Danielle's death is still a matter of speculation.
There is evidence that she become uneasy about his constant attention, and was trying to keep her distance.
Tragically, she was unable to escape his obsession.
'Grieve properly'
The investigation into the disappearance and murder of Danielle Jones is the biggest operation ever undertaken by Essex Police. It has cost £1.7m.
Reluctantly, detectives have now called off the search for her body, but they stress that any new information will lead to the investigation being re-opened.
Behind bars, Stuart Campbell can expect an early visit from Essex Police, trying to provide some comfort for Danielle's parents.
"I will seek to re-interview Campbell," says Detective Chief Superintendent Steve Reynolds, the head of the force's crime division.
"I will appeal to him to co-operate so Tony and Linda Jones can at least have a funeral service for Danielle and grieve properly.
"I am determined to find her body."
