Tabatha Lacerda Tozzi, 26, was shot in the head on the morning of April 22, 2023, in the 8100 block of Leger Drive in Las Vegas after an argument with her boyfriend, Oswaldo Natanahel Perez-Sanchez. Tozzi, an aspiring model and nightclub waitress, had told friends and her mother in the days before that she was unhappy and afraid while trying to end the relationship.

Tozzi was taken to a trauma center and placed on life support; she died on April 24, 2023, and her family arranged organ donation. The Clark County Coroner ruled her death a homicide on May 2, 2023, and the Las Vegas Metropolitan Police Department publicly identified Perez-Sanchez as the suspect that same day. An extensive manhunt followed, with federal agencies involved and rewards offered for information leading to his capture.
