Convicted killer Peter Tobin, from Johnstone, Renfrewshire, has been found guilty of murdering his third victim - 18 years after the event.
The body of 18-year-old Dinah McNicol was buried in the garden of his former home in Margate, Kent, close to that of another teenager Vicky Hamilton, who he had killed earlier in 1991.
He has also been convicted of murdering Polish student Angelika Kluk in 2006.
Like many 18-year-olds recovering from the hard slog of A-levels, Dinah McNicol was keen to spend the summer of 1991 having fun.
A music lover, she enjoyed the festival scene and in August went with friends to the Torpedo Town free event in Liphook, Hampshire.
Dinah McNicol never lived to receive her A-level results
Her family, in Tillingham, Essex, never saw
"happy, bubbly" Dinah
Standing just 4ft 10in (1.47m) tall, she appeared younger than her years but was known for being sensible.
Dinah had chosen to stay an extra night after her friends left the festival,
sharing a tent with David Tremlett,
who she had met at the event.
The pair tried to hitch-hike home - as Dinah had done without problem many times before - and Mr Tremlett was dropped off at junction 8 of the M25.
Dinah stayed with the driver - who we now know to be Tobin - and was never seen again.
Soon afterwards, her building society account was emptied via frequent withdrawals at cash points along the south coast.
Described by police as
"an intelligent and vibrant young woman who had her whole life ahead of her",
the £2,000 that disappeared had been the youngster's fund for education and travel.
One of her old teachers at Chelmsford County High School for Girls, Melanie Gulliver, recalled her as "very sweet, working hard and wanting to do well", despite a difficult past.
Dinah's childhood had been marred by the death of her mother Judy in a car crash when she was just six.
However, she was never able to collect the A-level pass marks that might have sent her to university.
A photograph issued early during the police investigation showed Dinah sporting a gothic look.
At the time she disappeared, she wore her dark hair in dreadlocks or plaits - often covered by a headscarf.
This hippy style was complemented by clothes from charity shops and jewellery she made herself.
She was last seen wearing Dr Martens-style boots and carrying a green drawstring bag.
Her belongings helped identify the body,
which was eventually found in a shallow grave at the edge of the patio in the garden of Peter Tobin's former house in Irvine Drive, Margate, Kent.
The find prompted her father, Ian -
who told the Daily Mail he had considered suicide
during 16 years of agonising over his daughter's fate - to say he would be able to "die in peace".
her school set up a fund in Dinah's name
to raise cash for the Essex Police Benevolent Fund and the Missing People charity.
When Vicky Hamilton's mother Jeanette called police to report her daughter missing at 0120 GMT on 11 February 1991, it sparked one of Scotland's biggest-ever missing person inquiries.
Nearly two years later, Mrs Hamilton would die without learning her daughter's fate.
Vicky Hamilton had been nervous about making the journey home alone
The 15-year-old had been eating chips while waiting for a bus in Bathgate, West Lothian.
She had spent a snowy weekend shopping, socialising and chatting with her sister Sharon Brown in nearby Livingston.
On the Sunday evening,
she gave Vicky a tight hug at the bus stop to calm her nerves
about making her way home alone and repeated instructions on where to change buses in Bathgate.
She was described by detectives as
"a pretty lonely, insecure wee girl on that journey".
Her body was eventually found in the garden of the house in Margate, Kent, where her killer Peter Tobin lived. It is not known whether he had grabbed her off the street or she had accepted a lift.
Reverend Geoffrey Smart, minister of Redding and Westquarter, in Falkirk, spoke at Vicky's funeral of a "bright, bubbly" girl who was full of fun.
A pupil at Westquarter Primary School and Graeme High School,
she loved animals and in particular enjoyed riding horses, he said.
After Tobin's conviction for Vicky's killing,
sisters Sharon and Lindsay and brother Lee released a statement
which said: "Vicky was much more than the girl who was abducted and killed by a stranger or the girl on the missing poster.
"Our sister was a warm, clever girl, who shared many happy years with us."
Vicky had not been without her troubles.
During Tobin's trial, it emerged
Vicky had posed for videos and photographs in suggestive poses,
including with a whip.
Her black leather purse, found near St Andrew Square bus station in Edinburgh days after she disappeared,
contained a note with "Samaritans" scribbled on
it and an oral contraceptive leaflet.
About 100 police officers had interviewed more than 7,000 people, taken 4,000 statements and seized 12,000 documents during the investigation.
The discovery of the purse - with its small amount of cash and a bus ticket - led officers to believe that Vicky, who had only £20 in her bank account and few clothes with her, may have run away to London or abroad.
This theory prompted American rock group Soul Asylum to use her photograph in the video to 1993 hit Runaway Train, along with that of Dinah McNicol.
It took 16 years for the truth of the situation to be revealed.
A 23-year-old student from Skoczow, Poland, Angelika Kluk was spending her second summer at the chapel house of St Patrick's Church in Glasgow in 2006.
She had "integrated into the family" at St Patrick's Church during her holidays from Gdansk University the previous summer, according to parish priest Father Gerry Nugent.
Angelika Kluk was described as a devout Catholic
However, it was in that very church that her life was to end when she was killed at the hands of Peter Tobin before her body was dumped in its vault.
During Tobin's trial,
Angelika's tearful father Wladyslaw Kluk spoke of his daughter's devotion to the church
and her love for Scotland.
"She was a prime student. A very good student," he said.
"She was going to special religious groups with the church and she was gaining a lot from being in church."
According to her older sister Aneta, Angelika was "very serious and a very responsible person - maybe even more than her age should allow her to be".
Nevertheless, Angelika had an "extraordinary enthusiasm" for life, she added.
She had clearly made a good impression at St Patrick's, where she was given free accommodation in return for cleaning work and was saving to fund her studies.
Fr Nugent said he was "full of admiration for her".
"She had a great vitality and desire to live and was good to talk to."
the priest later angered her family
by claiming to have had an affair with her - something they strongly denied.
Aneta did, however, accept her sister had been in a relationship with Martin MacAskill, a married man of 40.
Angelika's diary revealed her feelings after they met: "Martin is a very nice man. It is a pity most nice men are already taken. He is not too old either, merely 40."
A later entry read: "I have never missed anyone as much as I miss Martin even though he was here just a short time ago."
For his part, Mr MacAskill left a love note for Angelika in a copy of the classic Harper Lee novel To Kill a Mocking Bird discovered in her room.
An inscription in it read: "To Angela. I will always carry your song in my heart. You are my aghrai [darling]. I will always love you."
Angelika knew Tobin as
Patrick McLaughlin, the false name he used while working as a handyman
at the church.
She had worked with him on odd jobs. When Aneta arrived at the church after Angelika disappeared, Tobin had offered to help her.
Little did she know he was her killer.
