Evil mechanic folds his arms in police mugshot hours after raping and murdering lifelong family friend
Staring defiantly at the camera with his arms folded, a murderous mechanic poses for his mugshot - just a day after raping and killing his lifelong family friend.
Peter Kibisu sexually assaulted and strangled to death 31-year-old lawyer, Elizabeth Nnyanzi, at her family home in Harrow, London, after being rejected by a girl at a party.
The 23-year-old's callous mugshot was released by police today as he was jailed for life - with a minimum term of 27 years - for the brutal August 2015 killing.
Kibisu, a lodger in Miss Nnyanzi's £600,000 home, was branded 'calculating' and a 'wolf in sheep's skin' by the victim's mother Coleen, who had offered him a roof over his head when he was homeless.
He attacked the Imperial College graduate and paralegal, who worked at London firm Herbert Smith Freehills, at the family home on August 14.
The technician at a BMW dealership then went to work and later told police an attacker had broken into the house.
He subsequently called Miss Nnyanzi's younger sister, informing her of the news.
The Old Bailey heard Kibisu lived with Coleen and Miss Nnyanzi for nine months, but while Coleen was away in Guyana, "very close" family friend Kibisu raped and strangled her ex-Cheltenham Ladies' College daughter.
The rapist sobbed in the dock as prosecutor Mark Heywood QC told how Kibisu returned home on August 14 last year after a girl at a party rejected his sexual advances.
He said: "The defendant returned home to where he was living with very close family friends, having been out for almost the entire night.
"He then took the very gravest advantage of those who had given him a home by first sexually attacking and then killing Elizabeth Nnyanzi - one of the daughters of the house - who was then alone in the property and in her own bedroom."
Coreen and Kibisu's mothers had been friends since their twenties and he added: "The association between the two families had been close and long-standing... and in the case of the defendant he had been given a home by the Nnyanzi family for approximately nine months."
At the time Miss Nnyanzi's solicitor father Joseph lived in Uganda, while her two sisters Antonia and Cressida also lived away and Kibisu moved in on an "extended guest invitation."
He telephoned police at 6pm the following day.
Police were told Miss Nnyanzi had been attacked by an intruder.
Kibisu used tools to make it appear the patio doors were forced open, and sent texts to Miss Nnyanzi's phone in a "deliberate" attempt to cover his trail.
She was discovered dead in her bedroom and a post-mortem examination later showed she had died of asphyxiation.
"There was no intimacy between them and never had there been," said Mr Heywood.
"She looked down on him as a much younger cousin, and one account says that Elizabeth would have been horrified and rejected any such advance."
A victim impact statement from Coleen said her life had been "shattered" and said: "Elizabeth was a kind, caring and loving eldest daughter who used her extensive knowledge to help others.
"She would always go beyond the call of duty to help others.
"Now we no longer benefit from her guidance and help, and we can't begin to comprehend how Peter Kibisu has turned on us.
"At the request of his mother Mary, we helped him in his hour of need.
"He was homeless and we took him in.
"How did he repay us?
"He raped and killed our daughter."
Kibisu was arrested by police a day after the rape and murder.
He was charged with the crimes on August 17.
Jailing Kibisu for life, Judge Richard Marks said his crimes were "a horrendous betrayal of the trust and hospitality" extended to him.
"That is a home in which you two lived - the situation being your respective mothers had been friends for very many years," he said.
"When you found yourself homeless in around November 2014, Elizabeth's mother, out of the kindness of her own heart, took you in.
"Such was the closeness of your relationship with them, you referred to Elizabeth as being your cousin and her mother as being your aunt.
"You had a close friendship with Elizabeth, albeit she was about seven years older than you.
"There was no suggestion at all it was one involving intimacy."
Judge Marks said Kibisu had tried covering up he was responsible for her death.
"What had happened, was that shortly after you came home that morning substantially under the influence of drink and drugs, you had raped and then strangled her," he continued.
"She was a talented musician, a deeply loved sister and daughter and her family have been understandably devastated by what became of her at your hands."
Judge Marks added that she was an "outstanding" individual with huge potential ahead of her.
"What you did that morning was truly shocking.
"Your acts were those of unspeakable wickedness and it's frankly hard to comprehend how you could have done that to anybody, still less to a young person like her, who was to all intents and purposes family.
Wearing a grey suit and blue tie today, Kibisu sobbed as his handwritten letter was read out.
"I can only express my deepest regret to you all for having caused you so much pain, but also recognise sorry will never be good enough," he said.
"I know nothing can bring Elizabeth back and for this I am truly sorry and remorseful.
"I appreciate everything you have done for me.
"You took me in like a son and I abused the position of trust.
"This was not the way I intended to repay you for all your kindness."
Nnyanzi completed her bachelor's degree in medicine at Liverpool University and master's at Imperial before switching to law.
Described as "truly unique" by her sisters, she had worked for several charities and only returned from working in Uganda months prior to her death.
In a statement released by the Met Police today alongside Kisibu's mugshot, Detective Chief Inspector Tim Duffield said the murderer had carried out a 'callous attempt to conceal the truth'.
Det Chf Insp Duffield, of the force's Homicide and Major Crime Command, said: "Not only did Peter Kibisu brutally rape and murder a lifelong family friend in her own home, he then went on to concoct a version of events in a callous attempt to conceal the truth.
"Kibisu had ample opportunity to admit his role in Elizabeth's death at an early stage, but instead chose to put her family through the further ordeal of a potential criminal trial.
"It was only when confronted with a whole raft of evidence gathered during the police investigation that he finally accepted his guilt.
"Elizabeth's friends and family have been cruelly robbed of a caring, intelligent and hugely gifted young woman.
"My thoughts go out to them at this very difficult time."
Miss Nnyzanzi's family paid tribute to a 'beautiful' woman in a tribute following today's sentencing.
In a statement, they said: "Elizabeth Nnyanzi was a beautiful, clever, vibrant, and loving daughter, big sister, relative, and friend to many.
"Her life was cruelly cut short by this heinous crime which we will not allow to destroy our family.
"Instead we shall continue the good work she started as a way to honour her memory, and her great belief that good triumphs over evil.
"The careful investigation by the police and the thorough analysis of the case by the Learned Judge has meant that our faith in the justice system has not been shaken.
"We are relieved that Peter Kibisu, who murdered and raped Elizabeth, will be imprisoned for a long time, so that he will no longer pose a threat to the public.
"Peter's family and our family grew up together and we regarded him as part of our family.
"We could never have imagined that our trust could have been betrayed in this way.
"His wicked and selfish act has also greatly damaged friendships made over a number of decades.
"We want to thank everybody who has genuinely supported us.
"It has been the longest wait of our lives, but our faith in the legal system has remained strong and justice for Elizabeth has prevailed.
"We will always remember Elizabeth as a people's person and we will remain in touch with her extensive supportive network to bring about positive change.
"Her memory will live in our hearts forever. Thank you."
Kibisu pleaded guilty to rape and murder in November and December last year
