Mangum is accused of attacking Reginald Daye with the kitchen knife during an argument in April 2011. Daye died 10 days later. Mangum claims self defense, saying Daye attacked her.
In court Monday, prosecutors used a crime scene investigator to show jurors photos of the apartment Mangum and Daye shared with Mangum's children. Inside, several knives - some with broken blades and handles - could be seen scattered throughout the home.
A forensics specialist testified blood could be seen on one knife.
Mangum maintains Daye kicked down a bathroom door and dragged her by her hair before he was stabbed. Photos taken of her later at the police department reveal she had a slight injury under her left eye, a swollen lip, and what appeared to be blood stains on her clothing.
The prosecution could wrap up its case as soon as Monday or Tuesday. It's not clear if Mangum will testify on her own behalf when her defense gets to present its case.
Mangum made national headlines in 2006 when she accused a group of Duke University lacrosse players of sexually assaulting her while she worked as a stripper at a party. The accusations were later found to be false, and Attorney General Roy Cooper dismissed all charges filed against the students.
The prosecution could wrap up its case as early as soon as Tuesday. Testimony resumes at 9 a.m.
