Prosecutor Olivier Elsig told a news conference Friday in Switzerland that investigations into the cause of the crash are continuing.Initial findings indicated that the bus had not been speeding and that no other vehicle was involved, he said.Elsig also said he had no evidence to support media reports the driver may have been changing a DVD at the time of the crash.
Investigators are continuing to focus on three potential causes for the accident, Elsig said -- a technical issue with the bus, a health problem with the driver or human error.However, investigators have ruled out fatigue as the driver was well-rested and had only been driving for a short time, he said.Christian Varone, chief of police in Valais canton, told reporters that all those killed had been identified and their bodies flown back to Belgium.
Jan Eyckmans, a spokesman for the Belgian Ministry of Health, said two C-130 military aircraft had brought the bodies from Switzerland to Melsbroek airport in Belgium. A third plane transferred the luggage, he said.
Three medical planes are bringing back 14 of the injured Friday for treatment at a hospital in Leuven, Eyckmans said. Six children were flown back Thursday night.
Four children remain in the hospital in Switzerland -- one in Bern and three in Lausanne. It's "still too early, medically speaking," to move them, the spokesman said. Their parents are staying nearby.
The Ministry of Health has a crisis team in Brussels and one at each school in Lommel and Heverlee, he said. There are also people on the ground in Switzerland working on bringing everybody back, he added.
A spokeswoman for the mayor of Lommel, Greet Poets, said the town plans to hold a memorial service Wednesday, which the Belgian royal family is expected to attend.
Eyckmans said Belgians came together to pay their respects at 11 a.m. local time.
"All private companies, the government, institutions, radio, TV -- the whole country had a minute of silence, which was quite impressive," he said.
