An American woman found murdered in her Florence apartment was strangled with an object such as a rope or cord, a post mortem has revealed.
Prosecutor Giuseppe Creazzo said more lab results were needed to pinpoint the time of 35-year-old Ashley Olsen’s death.
Her naked body was found with bruises on her neck on Saturday.
Police think that she was killed on Friday after a late night at the Montecarla club, which has had its licence suspended three times after cocaine dealers were caught there.
Detectives have spoken to her boyfriend, Italian-American artist Federico Fiorentini, 42, and said he is not a suspect.
Her father Walter Olsen, an art professor who lives round the corner from his daughter’s apartment, called her “beautiful and creative” and said he had faith in the murder investigation.
