(CNN) -- A Texas woman is charged with murder after allegedly killing a college professor with a shoe.
Police say Ana Lilia Trujillo, 44, killed Alf Stefan Andersson on Sunday "by intentionally and knowingly committing an act clearly dangerous to human life."
Her bail was set at $100,000.
She had recently moved in with the victim, CNN affiliate KTRK reported, citing information the prosecution provided in court.
When police arrived at the apartment Sunday night, Trujillo answered the door with blood on her clothes and hands; the victim had 10 puncture wounds to his head -- some as deep as an inch and a half -- and 15 to 20 other puncture wounds along his face, arms, and neck, the prosecutor said, according to KTRK.
Trujillo told investigators that the man, her boyfriend, had grabbed her and a struggle followed, KTRK reported.
An official cause of death has not been determined, the Harris County Institute of Forensic Sciences told CNN.
It was not immediately known who Trujillo's attorney will be. CNN could not immediately reach a relative of Trujillo.
Jim Carroll, former manager of a motel where Trujillo lived, told KTRK that she had told him that "if anybody ever messed with her," she'd get them with her shoe -- "a big stiletto heel."
The University of Houston issued a statement saying it was "saddened to learn of the tragic death of Professor Stefan Andersson. Our hearts go out to his colleagues, family and friends during this difficult time."
He was a full-time research professor at the school's Center for Nuclear Receptor and Cell Signaling.
