On the morning of June 11, 2021, David Klene left the house he shared with 67-year-old Deborah Chong in northwest London.
Deborah was more than his landlord. She had allowed David to live in her home without paying rent after meeting him at church. She had also helped other people who were struggling financially.
But Deborah had been going through a difficult period.
During the COVID-19 pandemic, she became increasingly focused on YouTube videos about COVID-19, politics and lockdowns. According to the transcript, this increased her stress and anxiety. Her previously mild symptoms of paranoid schizophrenia also became much more severe.
By May 2021, doctors had intervened because of her worsening hallucinations. She received an antipsychotic medication, which reportedly reduced her symptoms but also caused serious problems with appetite and sleep. Deborah became weak enough that she sometimes needed David’s help to walk.
David was worried about leaving her alone while he went to work. A full-time caretaker had been requested, but one had not yet been assigned.
Then, on June 11, Deborah disappeared.
David Returns Home to an Empty House
After work, David returned home and called for Deborah.
There was no answer.
He searched the first floor and then went upstairs. When he called Deborah’s phone, he could hear it ringing inside her bedroom.
But Deborah was not there.
Her phone was lying on the bed. Her glasses were there too. These were items she normally carried with her.
David searched the rest of the house but found nothing.
He then contacted friends from church and other people who knew Deborah. Some people said her recent conversations had been incoherent and involved spirits, demons and the destruction of mankind.
David became concerned that Deborah had wandered away while experiencing a hallucination.
He called the police.
Police Check the CCTV Footage
At first, the CCTV footage seemed like it should provide an obvious answer.
Police expected to find footage of Deborah leaving the house. They planned to follow her movements from there.
But when they reviewed the cameras outside the property, something did not make sense.
There was footage of Deborah entering the house the previous day.
There was no clear footage of her leaving.
Police returned to the house and conducted a thorough search. They checked rooms, closets, the attic, basement and crawl spaces.
Deborah was nowhere to be found.
It would take nearly a month before investigators discovered what had happened.
Deborah and Jemma Mitchell
The key to the case went back to a friendship Deborah had formed at a church prayer group.
About 10 months before Deborah disappeared, she met 36-year-old Jemma Mitchell.
The two women became close despite their age difference. Deborah spoke to Jemma about her mental health struggles, while Jemma told Deborah about serious problems with her home.
Jemma had previously paid a contractor to renovate her house. According to the transcript, that contractor took her money without completing the work.
Jemma then hired another contractor. But when she could no longer afford to pay, the work stopped.
Her house reportedly had no working heating and a large hole in the roof. Jemma and her mother were living in those conditions.
Deborah decided to help.
The £200,000 Renovation Offer
Deborah offered Jemma £200,000 to complete the renovations.
There was one condition.
One room in Jemma’s renovated house would be dedicated to Christian ministry.
Jemma accepted the offer, and the two women began communicating regularly about the renovation. Deborah discussed things such as paint colors, while Jemma sent updates about contractors.
Their friendship also became closer. Deborah began calling Jemma her sister.
But their relationship changed dramatically in the months before Deborah disappeared.
Deborah Changes Her Mind
In May 2021, Deborah received the antipsychotic medication after her symptoms had become severe.
After that, she began communicating with Jemma much less.
When Deborah did contact her, she reportedly criticized Jemma for being messy and accused her of hoarding.
Jemma also noticed that Deborah no longer wanted to discuss the renovation.
Then Deborah made a major decision.
She told Jemma that she was no longer going to fund the renovation.
The £200,000 offer was over.
Deborah also told Jemma to sell her house and not contact her until it was sold.
For Jemma, this created a serious problem.
She did not want to sell the property because she considered it a family heirloom. But without Deborah’s money, she believed she had no way to complete the work.
She decided to visit Deborah one more time.
Jemma Visits Deborah on June 11
On the morning of June 11, Jemma arrived at Deborah’s house shortly after David left for work.
She rang the doorbell.
Deborah answered.
Jemma asked if she could come inside so they could talk about the renovation one more time. Deborah eventually agreed.
Inside the house, Jemma tried to persuade Deborah to reconsider.
She had prepared a speech about how much the renovation would mean to her and her family.
But Deborah refused.
According to the transcript, Deborah told her that the decision was final and that she would not pay for the renovation.
What happened next became the central event in the murder investigation.
The Suitcase That Hid Deborah
CCTV later showed two people leaving Deborah’s house.
At first, investigators did not recognize Deborah in the footage.
There appeared to be only one person walking down the street.
But there was a large suitcase being pulled behind her.
The person was Jemma.
According to the account in the transcript, Deborah was inside the suitcase.
The transcript says Jemma attacked Deborah inside the house with an unidentified blunt object. Deborah suffered a skull fracture and became unconscious.
Jemma then cleaned up blood inside the house and placed Deborah’s body in the suitcase.
She also took legal documents and a copy of Deborah’s will.
Jemma then left the house pulling the suitcase behind her.
Deborah’s Body Is Moved Away
According to the transcript, Jemma took the suitcase to her own house.
She left it in her backyard for about two weeks.
She later moved the suitcase about 250 miles away to a seaside town.
Deborah’s body was eventually discovered there by vacationers, who contacted police.
The discovery gave investigators the missing piece they needed to connect Deborah’s disappearance to Jemma.
Jemma Mitchell Is Arrested
On July 6, 2021, police arrested Jemma on suspicion of murder.
The arrest took place at her home. According to the transcript, officers forced their way through the front door, while Jemma was waiting inside.
During a search of Deborah’s house, investigators also found what the transcript describes as a fake copy of Deborah’s will.
The document reportedly left Deborah’s estate to Jemma and Jemma’s mother.
The Murder Trial and Sentence
In October 2022, Jemma Mitchell was found guilty of murder.
She was sentenced to life in prison with a minimum term of 34 years.
Despite the conviction, the transcript states that Jemma continues to maintain that she did not kill Deborah.
What Happened to Deborah Chong?
The disappearance initially looked like a case involving a vulnerable woman who had walked away from home.
Deborah’s phone and glasses were left behind. There was no obvious CCTV footage showing her leaving. Police searched the house but found nothing.
The breakthrough came from looking more closely at the CCTV footage.
What appeared to be one woman walking down the street was actually Jemma pulling a suitcase.
According to the account, Deborah was inside it.
The case then led investigators back to the relationship between the two women, the £200,000 renovation offer, and the decision by Deborah to withdraw her financial support.
Conclusion
The Deborah Chong disappearance began with an empty house and no obvious explanation.
David returned from work expecting to find Deborah at home. Instead, he found her phone and glasses but no sign of her.
Police initially struggled to understand how she could have disappeared without appearing on CCTV.
The answer eventually came from footage that investigators had initially overlooked.
The case ended with Jemma Mitchell’s murder conviction and a life sentence with a minimum term of 34 years.
The transcript’s account also shows how a friendship formed through a church community became connected to a disputed £200,000 property renovation and, ultimately, Deborah’s death.
