Guadalupe Concepion Ramos Swartz, 52, was one of the employees killed in a mass shooting at the Santa Barbara Processing and Distribution Center in Goleta, California on January 30, 2006. The shooter, identified as former postal worker Jennifer San Marco, entered the facility after following another car through a gate and taking an employee’s identification badge at gunpoint. San Marco used a 9mm semiautomatic pistol and shot several employees, including Guadalupe Swartz.

San Marco had been placed on psychological disability in 2003 after reportedly exhibiting erratic behavior at work. She purchased the firearm used in the attack from two pawn shops; background checks did not prevent those sales. Authorities were unable to determine a clear motive, though some reports noted San Marco had made racist comments. No other suspects were named.

If anyone knew Guadalupe Swartz, her work routine, or observed unusual activity at the facility around that date, please share what is known.
