The trail has finally started over the deaths at Love Parade Music Festival in 2010. Twenty-one people died on July 24, 2010 at the techno festival in the Western German city of Duisburg and nearly another 650 were injured.
The victims were killed and injured when a mass panic broke out in a packed tunnel that was the sole access point to the music event. People were crushed and suffocated to death.
Four event organizers and six city workers are on trial and appeared in Duisburg state court Friday. They face charged including involuntary manslaughter and bodily harm. They 10 deny the charges. Prosecutors also argue that there were severe mistakes in planning the festival and there were enough safety precautions taken to prevent such a tragedy.
If convicted, the accused face up to five years in prison according to the BBC.
About 65 victims or family members of those in the tragedy are involved in the suit.
