Officials investigating the incident which left Michael Schumacher "fighting for his life" are to hold a press conference on Wednesday morning.

Following speculation in the hours that followed the German's accident, much of it highly sensationalised, in recent days a clearer picture of events surrounding the incident have emerged.

Along with the German's helmet, which was voluntarily given to the investigators, newly discovered video along with the testimony of witnesses has enabled local prosecutor Patrick Quincy enough evidence to be able to hold a press conference just 10 days after the incident.

In addition to the speed Schumacher was skiing at - now thought to be around 12 mph and not the 40 mph initially suggested, the investigators are looking at whether the area was clearly marked and in particular whether the rock which the German hit required special markings due to its close proximity to the piste.

It is also understood that the investigators are looking at whether the safety releases on the German's skis were working properly, previous reports suggesting that he had been momentarily distracted by the binding on one of his boots.

Meanwhile, in its latest update on the German's condition, the Grenoble hospital where he is being treated said he remains "critical".

"The clinical state of Michael Schumacher is stable as he's under permanent care and treatment," read a statement issued this morning (Monday). "However, the medical team in charge stresses that it continues to assess his situation as critical."
