(CNN) Police investigating an alleged kidnapping and sexual assault found a different woman's body stuffed in a suitcase at a home in Las Vegas.

The incident started Wednesday when a woman told Las Vegas police that she had been kidnapped and sexually assaulted at a residence by the suspect later identified as Gary Walker, 55.

When detectives went to the home, they were notified Walker had allegedly killed another woman at the same residence, and found a gruesome scene.

The victim was identified Friday as Morgan Amaya, 22. The cause of death was a gunshot wound to the head, said Clark County Coroner's Office specialist Candace Caterer.
