Jon Ismaili, 34, has been sentenced to life imprisonment with a minimum term of 18 and a half years for the murder of sex worker Catalina Birlea in Cambridge. The sentence was handed down at Cambridge Crown Court on Monday, June 29, 2026, following his conviction on June 26.
Details of the Crime
Ismaili, from School Lane, Waterbeach, visited the property where Catalina was residing in Chesterton Road on October 2, 2025. He remained there for approximately two hours. Upon his departure, a friend discovered Catalina unresponsive. She was pronounced dead at the scene. A post-mortem examination determined that her death resulted from neck compression.
After a search, Ismaili was apprehended on October 5, 2025. He had been covering his face and actively avoiding police.
Police Statement
Detective Inspector Mark Dollard of Cambridgeshire Police commented after the verdict: "Only Ismaili knows what happened at the property that morning and why he murdered Catalina. He left the house knowing exactly what he had done, covering his face and actively avoiding police. I am pleased officers were able to catch up with him so quickly through diligent detective work putting together a comprehensive investigation."
Risks to Sex Workers
DI Dollard added: "Catalina was working as a sex worker that morning, and this case underlines the risks faced by those in this industry. To those working in the sex industry who have experienced violence please report it to the police. We will listen, we will investigate without prejudice and we will support you."
Ismaili's life sentence with a minimum of 18.5 years ensures he will serve a substantial period before being considered for parole.
