On February 20, 2006, 34-year-old Mirna Palma-Roman and her co-worker Romelia Vargas were found shot to death inside their food truck near 91st Avenue and Lower Buckeye Road in Phoenix. The location was described as a quiet area with new construction. Initially investigators were unsure whether the snack truck killings were connected to a series of other violent attacks then terrorizing the city, because the method appeared different from attacks attributed to the Baseline Killer.

Ballistics later linked the firearm used in the snack truck murders to other crime scenes, and investigators consolidated these cases into a single investigation of a serial offender. A woman recognized a police sketch and identified the suspect as Mark Goudeau, a 41-year-old construction worker. DNA from a prior non-fatal assault tied Goudeau to the crimes, and he was arrested on September 6, 2006. Prosecutors charged him with multiple homicides and related felonies; a jury convicted him of many counts and he received multiple death sentences. Did anyone know Mirna or Romelia, or have information about that area in February 2006?
