PC Jamie Lewis and former officer Deniz Jaffer were found guilty of gross misconduct at a tribunal on Wednesday, with their actions described as “hurtful, dishonest and unprofessional”.
Lewis will be dismissed from the Metropolitan Police with immediate effect. Jaffer had already resigned from the force before the tribunal but would have been dismissed without notice if he were still a serving officer.
Both men admitted last month to sharing photos of the sisters – who were stabbed to death last year – at the crime scene in Wembley.
Assistant commissioner Helen Ball, the tribunal’s chair, said on Wednesday: “This was hurtful, dishonest and unprofessional behaviour of the utmost seriousness.”
She added: “I am sorry that our officers behaved in such a hurtful, disrespectful and criminal way. Their actions are shameful.”
Neither Lewis nor Jaffer attended the misconduct hearing, and neither disputed the evidence.
Both men pleaded guilty to misconduct in public office at the Old Bailey in early November.
They admitted to sharing photos of the bodies of Smallman and Henry on Whatsapp after they were assigned to guard the crime scene at a London park.
The Crown Prosecution Service said a probe found 33-year-old Lewis and 47-year-old Jaffer left their posts to approach the women to take pictures, risking contamination to the crime scene in the process.
Lewis edited one image by superimposing his own face onto the photograph with the victims in the background.
The pair have been warned that they face “lengthy” jail terms when they are sentenced next month for misconduct in a public office.
Teenager Danyal Hussein was sentenced to life in prison for the murder of Smallman and Henry in Fryent Country Park in northwest London in June 2020.
The Old Bailey heard he had made a handwritten pledge – signed in blood – to a demonic entity to kill six women every six months before killing the sisters.
