A woman has been convicted of murder in the US for stabbing her boyfriend with the stiletto heel of her shoe, hitting him at least 25 times in the face.
Prosecutors said Ana Trujillo used her 14cm high-heel shoe to kill 59-year-old Alf Stefan Andersson during an argument at his Houston home in June.
Trujillo's lawyer had argued the 45-year-old woman was defending herself during an attack by Andersson, a University of Houston professor and researcher.
The jury will begin hearing evidence in the trial's punishment phase Wednesday. Trujillo faces life in prison.
Before she was taken into custody, Trujillo could be overhead speaking in Spanish with some friends, telling them, "I loved him and he was crazy.''
During the trial, prosecutors portrayed Trujillo, a native of Mexico, as out of control on the night of the slaying.
Prosecutors told jurors that after a night of drinking, the couple began arguing and during the confrontation, Andersson was injured and fell on his back.
Trujillo sat on Andersson and repeatedly struck him in the face and head with her shoe, they said.
"This is not self-defence. This is a vicious murder,'' prosecutor John Jordan told the jury on Tuesday.
Jordan told jurors that Trujillo had a history of violence, reminding them two witnesses had told the court Trujillo had attacked them two weeks before Andersson's death.
Prosecutors also said that Trujillo did not have any injuries from her confrontation with Andersson.
In a video of Trujillo's police questioning played at trial, she told detectives Andersson attacked her and that she used the only weapon she had at her disposal - her shoe - to defend herself.
