Michael Schumacher's wife Corrina seemed to be in a good mood during a rare public appearance, suggesting that the situation may be improving for the racing legend.

Corrina had been invited to be the official ambassador World Equestrian Games in Caen, France. On Tuesday, Aug. 26, she was caught smiling along with spectators during the competition.

Ever since her husband Michael suffered a horrific skiing accident back in late 2013, Corrina has often stayed by his bedside. The seven-time F1 world champion had been in a medically-induced coma during the initial recovery phases in Grenoble, France. Schumacher was later moved from to a rehab facility in Switzerland.

Meanwhile, police are still investigating the theft of confidential medical files detailing Schumacher's treatment. Earlier in August, a man believed to be connected with the crime was arrested by authorities. The unnamed individual was apparently the manager of Swiss helicopter company Rega. He was later found hanged in his police cell, but Swiss authorities do not believe the suspect was murdered.

When Schumacher was transferred from France to Switzerland, air transportation was briefly considered. It was during this time that Rega was contacted. Afterwards, the plan was dropped when Schumacher was transported via ground ambulance to the University Hospital of Lausanne instead.

After the theft, major media agencies were offered the medical files in exchange for cash. The information in the document was never released, and Schumacher's manager Sabine Kehm has already threatened to sue any organization that publishes the dossier.

So far, more recent reports indicate that Schumacher is awake, but his actual condition remains unknown. It is not certain whether he will make a full recovery, even though representatives of the family insist that former racing driver is getting better. As of now, he has not been seen in public since the accident.

Schumacher will soon undergo an experimental treatment involving a microchip implant. Developed by Croatian doctors Darko Chudy and Vedran Deletis, the chip may help Schumacher walk and talk again.
