The Swedish police previously said that the tragic accident involving the four members of the band was “an unfortunate accident”, refuting rumours it was caused by drunk driving or suicide.
The band’s manager Craig Tarry drove the car past warning signs and barriers to drive under a raised road bridge and crash into the water near Södertälje on the evening of 13 February following a concert.
Tarry, 32, and band members River Reeves, Jack Dakin, Kris Leonard – all aged 19 – died due to head injuries, Cheshire Coroner Nicholas Rheinberg ruled.
Tomas Lowe, 27, meanwhile died due to drowning, the BBC reported a Warrington inquest found.
The coroner said the incident was “an awful tragedy” and that "the evidence did not reveal the cause of sequence of events".
The inquest also heard that Tarry was not found to have had drugs or alcohol in his blood.
The four band members were shown to have only a small amount of alcohol in their systems, post-mortem examinations showed.
