A Mexican woman in Houston took the phrase "killer heels" to heart by using her size 9 closed toe suede 5 1/2-inch stiletto heel to stab her boyfriend to death last June.

The 45-year-old woman, Ana Lilia Trujillo, was accused of attacking 59-year-old Alf Stefan Andersson in his Houston condo during an argument with her sharp shoe heel. According to prosecutors on the case, Trujillo stabbed Andersson at least 25 times on his head and face until he bled to death. Incidentally, testimony in the case revealed that Trujillo was gifted the $1,500 designer navy blue platform pump by the victim, reports KHOU.

Court records and police testimony have disclosed, according to CNN affiliate KPRC, that Trujillo, who recently worked as a massage therapist, answered the door with blood on her clothes and hands when authorities arrived at the scene. Andersson was found lying face up in a hallway with a stiletto by his head.

During the case, Trujillo's attorneys made the case that Andersson, a University of Houston professor and researcher for the Center for Nuclear Receptor and Cell Signaling, attacked her while under the influence of alcohol and her actions were self defense. But according to the prosecutors, the couple got into a heated argument and Andersson suffered a preliminary injury and fell on his back. While he was on the floor, Trujillo is believed to have sat on him, pinned him to the floor, and struck him in the face with her heel.

One of the major points made by prosecution was that the deceased had defensive wounds on his hands and wrists, while Trujillo, who recently moved in with the victim, did not have any injuries. That said, Trujillo's attorneys made the case that she did have injuries from the alleged attack.

Prosecutors have also pointed out that she never told the 911 dispatcher or the police that she was in danger, and neighbors reported hearing a man scream but never heard a woman yell. This, coupled with the testimony of a cab driver who drove the couple home--and reports Trujillo was angry and yelling on the ride to the condo--led to the verdict by the journey.

Ultimately, the jury deliberated for two hours on Tuesday and reached the verdict that Trujillo was guilty for murdering Andersson, a native of Sweden who became a U.S. citizen.

"They didn’t ask any questions, they all seemed like they were in a good mood," said defense attorney Jack Carroll to KHOU. "I thought it was in the bag. I was wrong."

When the verdict was read, Trujillo reportedly showed little to no emotional reaction apart from briefly closing her eyes. Trujillo, who faces life in prison, was taken into custody after the guilty verdict and mouthed "I love you" to her family as she was escorted out of the courtroom.

"I would submit to you that when you find her guilty of murder, you’re not telling her anything she doesn’t already know," said Prosecutor Sarah Mickelson.

The trial's punishment phase is slated to begin on Wednesday where the jury will hear testimony in the sentencing phase.
