A large oil tanker sailed over the wreckage of Indie band Viola Beach's car moments after it plummeted off a bridge that opened to allow the vessel through.
Kris Leonard, River Reeves, Tomas Lowe, Jack Dakin and their manager Craig Tarry, all aged between 20 and 33, died when their car plunged more than 24 metres from a highway bridge into a canal south of Stockholm.
According to the Daily Telegraph the latest disclosure raises the possibility that they could have survived the initial fall and instead been killed by the oil tanker.
Swedish broadcaster SVT reported the ship's captain thought the car's wreckage was a large mass of snow floating in the water.
The vessel received a green light to proceed under the bridge as the crash had not yet been reported.
A spokesman for the shipping company said no one realised the car had fallen from the bridge.
"There was no way we could have known if we had driven over a car. The vessel is much too large for that," said Daniel Backman of Sirus Shipping.
Swedish police said the oil tanker passing over the vehicle may help explain why the car was so badly damaged.
