A 21-year-old woman is in “serious condition” at Moscow’s Sklifosovsky Institute after posing for a selfie with a handgun on Thursday and accidentally firing the weapon into her temple, The Independent reports.

According to Russian authorities, the 9mm pistol is believed to have been left at the woman’s workplace by a security guard. From AFP:

Police are investigating how the woman, who was an office worker, got hold of the gun, a city police spokesman told RIA Novosti.

The security guard had left the gun at work two weeks earlier before going on holiday, the police spokesman said.

A police source told state news agency RIA that the owner of the gun could face up to 6 months in prison for negligent storage of firearms resulting in “grave consequences.”
