For 131 years, the severed head of a murdered Victorian widow was missing. Then builders working on David Attenborough’s property uncovered a human skull—and reopened one of London’s most gruesome murder stories.
In October 2010, construction workers digging on property connected to naturalist Sir David Attenborough’s home in Richmond, southwest London, made a discovery no one expected.
Buried beneath the ground was a human skull.
The remains appeared old, and their location immediately raised suspicions that they might belong to a woman whose murder had horrified Victorian Britain more than a century earlier.
Her name was Julia Martha Thomas.
Thomas was a 55-year-old widow living at 2 Mayfield Cottages in Richmond in 1879. Earlier that year, she had hired an Irish domestic servant named Kate Webster, a woman who already had a criminal history involving theft.
The relationship quickly deteriorated. Thomas became increasingly unhappy with Webster’s behavior and eventually dismissed her.
But Webster persuaded her employer to allow her to remain for several more days.
On March 2, 1879, an argument erupted between them.
According to Webster’s later confession, she attacked Thomas, knocked her down and strangled her to prevent her from screaming.
What happened afterward turned the killing into one of the most notorious crimes of Victorian England.
Webster dismembered Thomas’s body and attempted to destroy or conceal the evidence. Contemporary accounts and later investigations established that portions of the remains were boiled in a household laundry copper, while other pieces were packed into containers for disposal.
A box containing human remains was later recovered near the River Thames.
One of Thomas’s feet was also found separately.
But her head was nowhere to be found.
Without it, investigators at the time were missing one of the most important pieces of physical evidence in the case.
Meanwhile, Webster attempted something extraordinary.
For a short period after the murder, she reportedly assumed aspects of her dead employer’s identity, wearing Thomas’s clothing and dealing with people as though she now controlled the woman’s property.
Eventually suspicion closed in.
Webster fled to Ireland but was captured and returned to England. She was tried for Julia Martha Thomas’s murder, convicted and sentenced to death.
On July 29, 1879, Kate Webster was executed at Wandsworth Prison.
But one mystery survived her.
Where was Julia’s head?
For generation after generation, no one knew.
Then, 131 years later, builders began excavating behind property associated with David Attenborough in Richmond.
The skull they discovered was located on the former site of stables belonging to the Hole in the Wall pub, only a short distance from where Thomas had been murdered. Attenborough had purchased the neighboring former pub property for redevelopment.
Investigators began comparing the skull with historical records.
Radiocarbon dating placed it within a period compatible with Julia’s death. Its location matched historical accounts of where Webster may have disposed of the missing head.
The skull also contained injuries consistent with the known circumstances of the murder.
Investigators additionally found unusually low collagen levels, a finding considered consistent with the remains having been exposed to boiling—matching what was known about Webster’s attempts to dispose of Thomas’s body.
DNA could not provide the final answer because suitable relatives of Thomas could not be located.
Instead, police combined forensic examination, radiocarbon dating, census information, historical documents and the precise location of the discovery.
In July 2011, West London coroner Alison Thompson concluded that the skull belonged to Julia Martha Thomas.
The cause of death was recorded as asphyxiation and head injury.
After more than a century, the missing head from the famous “Barnes Mystery” had finally been found.
One particularly gruesome part of the story requires caution.
Modern retellings frequently claim that Webster rendered fat from Thomas’s remains and gave it to local or street children as “pig’s lard.”
That allegation appeared in accounts of the case and was repeated during the modern inquest. However, historians have noted that the claim was never firmly proved at Webster’s original trial and may have become exaggerated as the already horrific murder passed into Victorian crime legend.
The confirmed facts are disturbing enough.
A Victorian widow was murdered inside her own home.
Her body was dismembered and partially boiled.
Parts of her remains were scattered and dumped.
Her killer attempted to take over aspects of her life before fleeing.
And her severed head remained hidden beneath Richmond soil for more than 130 years.
Then an ordinary building project connected to the home of one of Britain’s most famous naturalists unexpectedly brought the final missing piece of the case back into the light.
Kate Webster had been convicted in 1879.
But it took until 2011 for Julia Martha Thomas’s missing skull to finally have its name restored.
