A CBS4 investigation has found multiple cases of dead men and women voting in Colorado months and in some cases years after their deaths, a revelation that calls into question safeguards designed to prevent such occurrences. 

One of the most glaring cases was that of Sara Sosa in Colorado Springs. She died on Oct. 14, 2009. However, CBS4 uncovered voting records that showed ballots cast for Sosa in 2010, 2011, 2012 and 2013. Her husband, Miguel, died on Sept. 26, 2008. But CBS4 unearthed records showing that a vote was cast in his name the next year, 2009.

Following the CBS4 investigation, the Colorado Secretary of State’s office reviewed the CBS4 findings and confirmed at least 78 dead voters remained eligible to vote. Lynn Bartels, a spokesperson for the Secretary of State’s office, said county clerks were notified and told to immediately remove those 78 names from voter rolls. Bartels said “It’s not clear why” those dead citizens were still being listed as eligible voters.
