HOUSTON (AP) A Houston jury is beginning to hear the case of a 45-year-old woman accused of killing her boyfriend with the stiletto heel on her shoe.

Ana Lilia Trujillo (troo-HEE'-yoh) could get up to life in prison if she's convicted of the death last June of 59-year-old Alf Stefan Andersson. Prosecutors contend she used the shoe to beat the University of Houston professor in the head, face and neck, that she stomped on him and strangled him.

Her attorney has said the couple had been out drinking and when a fight erupted later at Andersson's apartment, she was protecting herself.

The Houston Chronicle reports (http://bit.ly/1i863K2 ) Monday the trial is expected to last more than a week.
