Sophia Lisa Nunez, 37, was found dead in her Phoenix home on April 10, 2006. Her eight-year-old son returned home after not being picked up from school and discovered the bathtub overflowing; his mother was submerged with a gunshot wound to the head. The scene showed signs of a violent struggle and possible sexual assault, with her shirt pulled up and her bra undone.

Investigators linked her killing to a series of violent crimes in Phoenix from 2005 to 2006 attributed to a suspect known as the Baseline Killer. Ballistics and DNA evidence connected Mark Goudeau to multiple murders and other violent offenses, and records from their investigation show Nunez and Goudeau had known each other socially and spoken by phone hundreds of times. Goudeau was tried and convicted on charges that included the murder of Sophia Nunez and later sentenced to death.

If anyone knew Sophia, her routines, or had information about her contacts in early 2006, please share what is known.
