A man fatally stabbed a neighbor woman because she treated him "like dirt" and told him he smelled, Pittsburgh police said.
Terrence Andrews, 38, is charged with criminal homicide in the Thursday night death of 19-year-old Lisa Maas.
Andrews told them Maas insulted him that morning and he waited all day for her to return to her apartment, before attacking her with scissors, police said.
Maas tried to defend herself with a steak knife, officials said.
Andrews sat on Maas' couch and watched her die before leaving, police said.
He told police "Take me to jail. I did it," when they arrived, officials said.
Andrews is recovering from a cut to his head and will be jailed after his release from a hospital.
