An employee at a Fort Leavenworth hospital allegedly tried to kill his boss by lighting her on fire and then attacking her with a sharp blade.

The U.S. Attorney's Office says Clifford Currie threw a flammable liquid, possibly gasoline, onto his supervisor at Munson Army Health Center. He then allegedly set the liquid ablaze and assaulted her with a straight-edge razor.

Another worker told investigators she heard the victim's screams and saw flames covering her from the chest up. The other worker rushed to help the victim and was reportedly injured herself as Currie continued assaulting his supervisor.

Hospital employees managed to subdue Currie until authorities arrived to take him into custody, the U.S. Attorney's Office said.

Currie has been charged with a single count of assault with the intent to commit murder, prosecutors say. If convicted, he could face up to 20 years in prison and could have to pay up to a $250,000 fine.
