Transcript for Houston Woman Charged With Murder Claims Self-Defense
headline grabbing murder trial in Houston. The defendant is accused of stabbing her boyfriend to death with her stiletto heel. . Reporter: Her lawyer claims there is much more to this situation which he intended to show this court starting today. This morning, Anna Trujillo will walk into court for opening statements. The 45-year-old accused of brutally murdering her on-again, off-again boyfriend, among other things, striking him with her high-heeled shoe. She called 911 shortly before 4:00 A.M. On June 9th. They say she answered the door covered in blood. Inside they say they found 59-year-old Anderson, a medical researcher at the urt of Houston in a hallway and her stiletto right next to him. He appeared to have ten puncture wounds to the head and 15 to 20 along his face, arms, and neck. Reporter: According to police, the couple got into a fight at a nightclub after another man offered to by Trujillo a drink. The fight later continued at Anderson's apartment.
