Doris Maricela Aguilar, 25, was killed in Phoenix after a year-long campaign of stalking by a former coworker, 51-year-old Juan Jose Velis Cuellar. Doris had repeatedly changed gyms because Cuellar kept appearing in parking lots and sending threatening messages; she told family she feared he would be responsible if anything happened to her. Doris was last seen leaving home for a store on the evening of July 1 and did not return.

On July 7 a car parked near a west Phoenix shopping mall contained the bodies of Doris Aguilar and Juan Cuellar; both had been dead several days. The medical examiner later determined Doris died from a gunshot wound and that Cuellar died from a self-inflicted gunshot wound. Investigators say Doris was likely killed elsewhere and moved to the rental vehicle, where a note from Cuellar attempted to frame her death as a suicide; police have rejected that claim. Her own car was found abandoned with her wallet and belongings inside.

Anyone who knew Doris, her routines, or saw her between July 1 and July 7 is asked to come forward with information.
