A man is facing homicide charges after crashing his car while drifting in a snow-covered car park.
Canton Sankt Gallen prosecutors says the 20-year-old left his 23-year-old passenger in the upturned car after it slid down a slope into a small river.
The passenger was freed by firefighters, but he died shortly later in hospital.
The prosecutor’s office say two other people are also being investigated.
