Simon Levy has been found guilty of murdering two women and sexually assaulting a third, who escaped the violent attack with a broken collarbone.
Levy, 40, was found guilty of murdering Carmenza Valencia-Trujillo, 53, in March last year, and Sheryl Wilkins, 39, in August last year.
He killed both of the vulnerable women in the middle of sexual encounters in secluded areas of London.
Ms Valencia-Trujillo was found in the stairwell of Wendover House, a block of flats in Southwark, south-east London, on March 17 last year. Ms Wilkins was found dead four months later in a car park in Tottenham on August 24.
Levy was also found guilty of carrying out a violent sex attack against a third woman in the same Tottenham car park in January last year. The victim, who cannot be named for legal reasons, survived the attack but suffered a broken collarbone. In a majority verdict, the jury found him guilty of all six counts he faced.
