THE brutal murder of a 14-year-old girl who was childhood pals with serial killer Levi Bellfield remains a mystery 42 years later.
Patsy Morris was discovered dead on Hounslow Heath in June 1980 after she vanished from school on her lunch break.
The teen had been strangled with her stockings but there was no evidence she was sexually assaulted.
Chillingly her murderer has never been found and remains on the loose 42 years later.
There have been a number of theories over the years – including claims she may have been Bellfield's first-ever victim when he was aged just 12.
The fiend is serving life in jail after murdering Marsha McDonnell, 19, and 22-year-old Amélie Delagrange, as well as attempting to murder Kate Sheedy.

He was also convicted of murdering 13-year-old schoolgirl Milly Dowler.
Patsy went to the same school as Bellfield – Feltham Comprehensive – and was said to be a close pal of the serial killer's.
On June 16, she was seen leaving school during her lunch break to change into dry clothes after forgetting her rain coat.
A witness spotted Patsy shortly after near her home – the last time she was seen alive.

After she vanished, a huge search was launched involving hundreds of police officers and members of the public.
Patsy was discovered two days later on the heath just five minutes from her home.
She was lying face down on a path with her tights wrapped around her neck and a second pair tied around her wrists and body.
Her death horrified the nation and parents were warned not to let their children cross the heath alone as the killer was hunted.
Patsy's own parents were left stumped as the teen had been told never to cross the open space.
Her mum said at the time: "We can't understand what she was doing on the heath.
"She was always told not to go there and never disobeyed our orders."
SERIAL KILLER FEARS
Bellfield was known to regularly bunk off school and roam Hounslow Heath.
On the day Patsy was snatched, he had again played truant.
Bellfield was also obsessed with blondes – matching Patsy's hair colour – and once told his ex: "All blondes are s**gs and deserve to die".
Even more haunting, the killer allegedly made a confession to a cellmate over Patsy's murder.
In 2008, Scotland Yard revealed they were reviewing the potential new evidence after Bellfield reportedly boasted of murdering the teen when he was just 12 years old.
Following the bombshell, Patsy's dad George told how he received a phonecall from a teen boy after her murder – fuelling fears the monster was behind the killing.
But no definitive evidence was found linking the murderer to Patsy's death.
FRESH APPEAL
That same year, a man walked into a Norfolk police station and claimed he had murdered Patsy but was later found to be suffering from a mental illness that contributed to his confession.
Chillingly, Bellfield wasn't the only serial killer to be linked to the horrific murder.
Peter Tobin was thrown into the mix as a potential suspect after targeting young women during his reign of terror.
The monster, who was jailed for life for the murders of three women, was known to be in the London area at the time.
Patsy's murder was reviewed as a potential case that could be linked to Tobin under Operation Anagram but without any evidence, the theory was dropped.
Tragically, Patsy's parents have since died without ever finding out who killed their daughter.
In a fresh appeal for information, the Met Police told The Sun Online: "The investigation into the murder of Patsy Morris in Feltham in 1980 remains open.
