(CBS/AP) ERIE, P.A. - A Pennsylvania murder case may revolve around "the scent of a woman."

Prosecutors say Rachel Kozloff told her boyfriend she had "smelled sex" on him before she killed him earlier this year.

The 31-year-old Kozloff, from northwestern Pennsylvania, is on trial for the April 12 killing of her boyfriend of eight weeks, Michael Henry.

Investigators say Kozloff shot  Henry at his Erie apartment because she suspected him of cheating on her. Her then-10-month-old son was in a nearby room.

Kozloff has denied killing Henry but said he pushed her down the stairs during an argument.

Police never found the alleged murder weapon but found spent 9mm shells in Henry's apartment. Investigators say Kozloff had purchased a .40-caliber handgun and a kit to convert it to 9mm.
