Lilly Lindström was last seen alive on May 1, 1932, by her downstairs neighbor Minnie Jannson (per Gizmodo). A fellow sex worker, Jannson later told authorities that Lindström had approached her on that date and asked if she could have some condoms. On the following morning, Jannson was a bit worried when Lindström did not appear from her apartment. After several days of Jannson’s knocks on Lindström’s door going unanswered, the police were contacted (via Mysterious Universe). 

When police arrived at Lindström’s apartment on May 4, no one responded to their knocks, either. Letting themselves into the apartment, they saw nothing out of the ordinary in the living room, which was neat and clean, without any signs of a struggle. But when they advanced into the bedroom, they were greeted by a horrifying sight — Lindström was lying face down on her bed with signs of blunt force trauma to the back of her head. It appeared she had been dead for several days.
