HOUSTON (AP) - It started out as a normal night where Ana Trujillo and her boyfriend went out to a local Houston bar they often frequented. They enjoyed a couple bottles of wine, and tossed back a few shots of tequila.
But the evening soured, she told police, after another man approached her at the bar. He offered to buy her a drink, angering her boyfriend, Alf Stefan Andersson, a respected professor and researcher at the University of Houston. The two argued and left the bar in a huff.
Yet how she became so incensed, or scared, that she wielded her stiletto shoe as a deadly weapon - repeatedly bashing Andersson with the heel, leaving him dead in a bloody crime scene - remains unclear. Trujillo maintains she acted in self-defense after Andersson became violent.
"Somebody is dead. The motive doesn't change the charges," Sara Marie Kinney, a spokeswoman for the Harris County District Attorney's office, said Wednesday. "She confessed to doing it. The reason and all of that will play out in court."
Trujillo, 44, was charged with murder and remained jailed Wednesday. Bond is set at $100,000, according to court documents. Her attorney, Lott Brooks, said he has requested a physical and mental evaluation of Trujillo. He said she maintains self-defense, but he still has not been able to have a lengthy conversation with her about the facts of the case.
