Investigators have confirmed that Michael Schumacher was eight metres off-piste when he hit a rock and fell.
Also they added that the German was not able to decrease his speed before hitting his head on a rock eight metres off piste.
Seven-time F1 world champion, who has been in an induced coma since the December 29 following a skiing accident in the French Alps on 29th December.
But signs in the area were correctly marked and analysis of the footage from Schumacher’s helmet camera is “extremely legible”, reporters were told.
“With regard to the inquiry itself, it’s progressing well,” Chief Prosecutor Patrick Quincy said.
“We’ve had a number of hearings from the emergency services on the spot – people that rented the skis, witnesses. We had some analysis of the skis and the helmet. We also examined the film that was made on the camera that was fixed on Mr Schumacher’s head.”
“Mr Schumacher is in fact a very good skier, so he was going on the left-hand side in an area above what limits the main piste,” chief gendarme Stephane Bozon added.
“He was on terrain that was really more sloped and because of that slope there was certain speed. He tried to reduce the speed, but there were a few curves, so a parallel trace remained to the direction he was going in.”
“That particular film was extremely legible and confirms the information we had at hand, we will take advantage of this film to recreate the situation.” Mr Quincy explained.
“We will know the path that Mr Schumacher followed. The film will be examined and the technician will look at it.”
Schumi remains in a critical, but stable, condition in Grenoble hospital following last month’s accident. His manager, Sabine Kehm, said on Monday: “The patient’s privacy requires that we do not give out details of his treatment and it is for this reason that we do not envisage any new press conferences, nor to send out any written press releases, in the near future.”
