Prosecutors say a northwestern Pennsylvania woman told her boyfriend she had "smelled sex" on him before she killed him earlier this year.
Thirty-one-year-old Rachel Kozloff is on trial in the April 12 killing of her boyfriend of eight weeks.
Investigators say Kozloff shot Michael 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.
The Erie Times-News reports Kozloff's attorney deferred making an opening statement until he begins presenting his case.
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.
