Authorities found the woman in the apartment with the victim at The Parklane, luxury highrise condominiums in the 1700 block of Hermann Drive.
Another tenant called 911 around 4am Sunday, telling dispatchers someone was being assaulted.
When officers arrived, Ana Lilia Trujillo answered the door to a unit on the 18th floor. That's where they found the 59-year-old victim's body.
According to Houston police, the man was stabbed multiple times. The weapon investigators think she used: a stiletto heel.
Officers detained Trujillo and questioned her at the scene. They said she was initially cooperative, but she reportedly stopped speaking to investigators and was transported downtown for additional questioning.
Investigators said the victim lived in the apartment, but Trujillo did not and was visiting. Their relationship is unknown.
Residents at The Parklane were hesitant to talk about the crime. The few who did speak with us off camera admitted they were shocked by what happened.
Trujillo, 44, has been charged with murder.
The victim's name has not been released. The motive is unclear and the investigation continues.
