Autopsy results show that all victims died of suffocation, not the crash itself. This means they were alive when the bus had caught fire. Final analysis will give a final assessment of the causes of the accident, but the underlying root cause at this point is human error, Bulgarian Deputy Chief Prosecutor and Head of the National Investigation Service, Borislav Sarafov, told Thursday’s press conference.
Sarafov says the traffic barrier that the bus driver hit is not only unnecessary on the spot, but also dangerous.
There was no explosion, but what those who were nearby heard was the impact, the strong impact of the bus on the barrier on the right side, which I said had no place there. There was no explosion, Sarafov said.
Media report that there are 15 to 20 eyewitnesses, and there are no eyewitnesses. We have not questioned any eyewitnesses other than those who survived the accident. I will ask that there be no speculation and that it be reported professionally. There are no eyewitnesses. First, two of the passengers on the bus were questioned, who were awake and they gave accurate and objective information. They are questioned separately from each other and tell the same versions of the event. Two more of the survivors are being questioned, said Sarafov.
Some of the expert analysis are completed, and the autopsy of the victims are also completed.

The best auto-technical experts have been hired, and a fire analysis for the intensity of the fire has been appointed. An expert analysis will be conducted as to why the bus deviated from the road and what led to the tragedy. There are versions that there were fuel jerry cans. That version has been rejected by us. 3 cans were found, but there are remains of fuel used by the bus, and that’s not what caused the fire. “There are no fuel cans, except the usual ones, said Sarafov.
He rejected the version of a possible terrorist attack on the bus and added that part of the causes of the accident were the faded traffic signs on the highway.
