Kristin Nicole Gibbons was 26 when her body was found in Phoenix in spring 2006. She died of a gunshot wound to the head; her remains were badly decomposed when discovered after a foul odor led a local businessman back to a gravel parking lot where he had earlier noticed blood.

Investigators linked Gibbons’s killing to a series of violent crimes attributed to a serial offender labeled the Baseline Killer, whose pattern involved approaching victims at gunpoint, often sexually assaulting them and then shooting them once. A DNA match from a September 2005 sexual assault tied Mark Goudeau to the investigation; he was arrested September 6, 2006, and a search of his home reportedly yielded a ski mask with traces of Gibbons’s blood.
