Mischa Ebner was born in 1975 in Switzerland. At the age of four, he and his older brother Alex were found neglected and abused, leading to their placement in an adoptive family in 1979. Mischa discovered a passion for endurance sports, particularly running and cycling, which served as an outlet for his inner turmoil.

In 1998, Mischa achieved national recognition by winning the prestigious Frauenfelder Waffenlauf, a military endurance race. Tragically, three days after his victory, his brother Alex committed suicide, a loss that deeply affected Mischa.

Professionally, Mischa worked as a cook in various establishments in Bern and was actively involved in the local running community. Despite his outward appearance of normalcy, he struggled with unresolved psychological issues stemming from his traumatic childhood.

Between 2001 and 2002, a series of assaults and thefts targeting women occurred in the Bern area. The attacks escalated in violence, culminating on August 1, 2002, when Mischa fatally stabbed 20-year-old Natalia Patricia Slupski in Niederwangen and severely injured another woman in Bümpliz.Murderpedia

The police investigation revealed that Mischa had committed numerous offenses, including 29 additional crimes such as thefts and assaults. He left handwritten notes at some crime scenes, and DNA evidence eventually led to his arrest on August 19, 2002.

While in custody, Mischa confessed to the murder and other crimes. However, before he could be tried, he committed suicide on November 24, 2002, by hanging himself in his prison cell.
