A U.S. grand jury on Wednesday indicted a civilian hospital employee on charges of attacking and injuring two women, one of whom he set on fire. Officials say he attacked the other woman when she tried to help the first victim.

Acting U.S. Attorney Tom Beall says Clifford Currie, 54, Leavenworth, Kan., is charged with one count of assault with intent to commit murder and one count of assault with a dangerous weapon.

A criminal complaint filed Sept. 8 in the case alleged that Currie threw gasoline or some other inflammable liquid on his supervisor, Katie Ann Blanchard, lit her on fire and assaulted her with a straight edge razor and scissors. Co-worker Deanne Killian came to the Blanchard’s aid when she heard screams and saw Blanchard on fire from the chest up. Killian was injured trying to put out the fire and stop Currie from continuing the assault on the Blanchard.

Currie was subdued by hospital employees and then arrested.

If convicted, he faces a penalty of 20 years in federal prison and a fine up to $250,000 on the attempted murder count, and up to 10 years and a fine up to $250,000 on the other count.
