A jury is to hear a third day of testimony in the trial of a Houston woman accused of stabbing her boyfriend to death with her stiletto heel.

Ana Trujillo (troo-HEE'-yoh) is charged with murder in the death of 59-year-old Alf Stefan Andersson. Investigators say Trujillo struck him at least 25 times in the face with her shoe during an argument at his Houston condominium in June. Trujillo's attorney says the 45-year-old woman was being attacked by Andersson and used the shoe to defend herself.

On Wednesday, the Harris County jury is scheduled to watch a video of Trujillo's police interrogation about the night of the slaying.

On Tuesday, jurors were shown the blue suede stiletto heel that prosecutors say was used as the murder weapon.
