Patricia Calhoun-Murdock, 29, is facing charges Monday after she allegedly wore a "Scream" mask while stabbing another woman.
Prosecutors said Calhoun-Murdock broke into an apartment and attacked a woman on September 1, in the 4400-Block of South Union in Canaryville.
Calhoun-Murdock was arrested this past Friday, nearly two weeks after the attack, and had her first appearance in court Sunday.
She is charged with attempted murder, home invasion, and residential burglary.
Investigators said the crime appears to be random.
