Martha Anaya, 28, was kidnapped from Santa Ana, California, on November 12, 2013, and was later raped and murdered at a paint and body shop in Anaheim. Two convicted sex offenders, Franc Cano and Steven Dean Gordon, were identified as her kidnappers and killers. Investigators linked the pair to a series of killings of vulnerable women in Santa Ana and Anaheim, including Kianna Jackson, 20; Josephine Vargas, 34; and Jarrae Nykkole Estepp, 21.

DNA evidence and data from GPS-tracking devices the men were required to wear were instrumental in building the case. Endeavours to find Anaya, Jackson, and Vargas did not recover their bodies; Estepp’s body was found on a conveyor belt at a recycling plant in Anaheim and helped connect the suspects to the other crimes. Franc Cano pleaded guilty and received life without parole; Steven Dean Gordon was convicted and later sentenced to death. The case prompted criticism of probation officials after it emerged the two men had been able to socialize and commit these crimes while under GPS monitoring.

If anyone knew Martha Anaya, her routines, or activity around Santa Ana and Anaheim in late 2013, please come forward with any information.
