An Offence Report was taken and will be forwarded to the Postal Inspector for investigation.Cochran was one of the residents who received a notification that his mail-in ballot arrived the same day."Whether it was to hopefully get some credit cards and do something fraudulent, or if they were trying to disrupt the election process, either way, both of those are bad outcomes," said Cochran.The United States Postal Service said the ballots weren't sent out Friday night. They said the update residents received was to notify them that the ballots had arrived at their local delivery station, but they would be sent to homes on Monday.You can track the location of your mail-in ballot or request a replacement ballot on the Colorado Secretary of State page.
