A 36-year-old man, Koci Selamaj, was jailed for life with a minimum term of 36 years by a court in London on Friday for the murder of a British-Bangladeshi woman, Sabina Nessa.
Bangladeshi media outlets say that the ancestral home of Sabina Nessa is in the Sunamganj district of Bangladesh.
According to BBC, Koci Selamaj killed Sabina Nessa in a park in Kidbrooke, south-east London in September 2021.
CCTV footage captured him striking the 28-year-old over the head until she was unconscious, before carrying her away. He then strangled her, removed some of her clothes and tried to hide her body.
Selamaj, a garage worker from Eastbourne in East Sussex, travelled to London on 17 September intending to assault a random woman after he was spurned by his estranged wife, the Old Bailey heard.
Nessa, who taught a year one class at Rushey Green Primary School in Catford, was found nearly 24 hours later near a community centre in the park.
Days later, Selamaj, from Eastbourne, East Sussex, was arrested in the seaside town and pleaded guilty to murder in February.
On Friday, he refused to come to the Old Bailey and was sentenced in his absence.
Justice Sweeney described the "savage" attack as sexually motivated. He said Ms Nessa was the "wholly blameless victim of an absolutely appalling murder which was entirely the fault of the defendant".
It is believed Ms Nessa had only gone through the park as she was running late and this was the quickest route to the bar where she had been due to meet a friend.
Grainy footage showed a hooded man passing her, looking back at her, and running toward her before hitting her over the head 34 times in quick succession.
He used such force that parts of the weapon - a metal traffic triangle - shattered and fell to the ground, the Met Police said.
Ten minutes after dragging Nessa away, Selamaj reappeared on camera and began picking up pieces of the murder weapon from the floor. He also used tissues to clean the bench where part of the attack had taken place.
On his way back to the south coast, Selamaj dumped the warning triangle in the River Teise in Tunbridge Wells, Kent.
Police said he appeared to be "calm and collected" on his arrest.
On being cautioned by an interpreter, the Albanian national said: "What will happen if I open up now and say everything?"
Lewis Power QC said his client Selamaj had provided no explanation for why he killed Ms Nessa, adding: "He simply accepts that he did it."
Justice Sweeney said Ms Nessa's death added to "the sense of insecurity" particularly felt by woman walking through the city at night.
"She had every right, as her family said, to be walking through the park all glammed up and out to enjoy herself after a long week at work. The defendant robbed her and them of her life," he said.
The judge said it was "cowardly" of the defendant to refuse to attend his sentencing but said he had no power to force him.
'You are an animal'
Following the sentencing hearing, Det Ch Insp Neil John described Selamaj as an "evil coward".
He said: "It is highly unusual for someone to go from zero to a crime of this magnitude. We are pleased Selamaj will spend the majority of his life in prison."
Addressing the teacher's absent killer on Thursday, Ms Nessa's parents Abdur Rouf and Azibun Nessa said in a statement: "You had no right to take her away from us in such a cruel way.
"The moment the police officer came to our house and told her she was found dead our world shattered into pieces.
"How could you do such a thing to an innocent girl walking by, minding her own business?
"You are not a human being, you are an animal."
