A teenager who lured a prostitute into an alleyway and then stabbed her to death has been jailed for life.
Mateusz Kosecki, 18, admitted murdering mum-of-two Yvette Hallsworth behind houses off Hartington Street, Normanton, Derby.
He was jailed for life at Nottingham Crown Court with a minimum of 24 years.
During the investigation it was discovered Kosecki "preyed" on and attacked other prostitutes in the area, but they were unreported.
The body of Miss Hallsworth, who was described as a loving mother, was found on the morning of 6 April by a passing member of the public.
Kosecki, originally from Poland, led his victim to the area close to his home in Hartington Street, before stabbing her 18 times, searching her body and running off.
At a hearing on Tuesday he admitted murder but denied two charges of attempted robbery and one of attempted rape, which he will face no further action for.
The court was told that he planned to rob his victim in a desperate attempt to get enough money to return to Poland and went out armed with a kitchen knife.
In sentencing Kosecki, Judge Michael Stokes QC, said he killed Miss Hallsworth in a "cruel and savage way" and her last moments would have been of abject terror.
Det Insp Graham Prince said he hoped the sentence would bring some comfort to the victim's family.
He said: "Kosecki made a plan and lured Yvette to a dark, secluded location before attacking her with a knife. She sustained a number of stab wounds which caused her death.
"After he had killed her, Kosecki searched Yvette before running off and leaving her where he had murdered her.
"The evidence against him was overwhelming, which may be the reason he has pleaded guilty."
Det Insp Prince wants women who work in the sex trade to be more confident in reporting crime.
"It is clear that Kosecki was a predator who preyed on a number of vulnerable women in this area, knowing that these matters would probably go unreported," he added.
