Friends of 55-year-old Marianne M. laid flowers and messages at a memorial outside the apartment block where she was killed in Berlin on Friday, after a police investigation concluded her death was the result of murder during 'sex games'. Suspects Taifun S. and Jasmine P., 36 and 27 respectively, met the victim after arranging to meet on a social media site. Following her 'sex game' torture and... Еще subsequent murder, the couple dragged the body down four flights of stairs, wrapped her in a cloth and left her outside. A forensics investigation concluded that the cause of death was due to 'gratuitous violence.' The couple was arrested at Schonefeld airport, attempting to leave for Turkey. Both have remained in custody since late December. Both are known to police for various offences including drug trafficking, dangerous bodily harm, weapons laws violations and theft.
