The accident is puzzling – films and interviews should provide answers

A purple spray paint on the grass marks the contours of the bus, where it was after leaving highway 25 on Monday afternoon. All around you can see the remains of a rescue effort – blue latex gloves, paper napkins and traces of blood. But also remnants of everyday life – soda bottles, post-it notes and a school student's notebook, the pages of which are flipped back and forth in the wind by the motorway.

Wheel tracks from the accident bus are clearly visible in the ditch, far in towards Växjöhållet. Following them, we find two yellow spray paint markings - maybe 200 meters further. There, the bus seems to have left the road for the first time.

That explains the testimony given by one of the travelers. That the bus vibrates for a long time before it overturns. The uneven ground in the ditch must have undeniably created a shaky ride.

The bus driver who has been detained since this morning has not yet been heard other than for information, without a defense attorney.

- He is aware of what happened, but has not really given any explanation, says the head of the investigation, prosecutor Tommy Sköld.

Now the police are analyzing filmed material from the bus and other possible sources while interviewing witnesses. Only when that information has been collected must the driver be interviewed thoroughly.

- I think it won't be until Wednesday. I have until Thursday before I have to make a decision about possible detention, says Tommy Sköld.

At the regional transport bus depot, the mood is tense. One of their colleagues is in police custody and one of their buses has caused the death of a young man.

- Heavy, heavy. Busy, busy, says a man who is roughly the same age as the arrested 60-year-old.

Another wonders if it might have been the wind that caused the run? The driver involved was experienced, but double-deckers are known to be more rank-and-file than regular buses.

- I don't think that's the explanation here, says Pär Welander, traffic director at Region Kronoberg.

- At wind speeds of 25 meters per second and more, the Swedish Transport Administration advises against driving with double-decker buses, but yesterday it only blew 8, he says.

The traffic director offers his condolences to all those affected and says that he must now await the police investigation.
