The Jefferson County, Missouri, sheriff's office has apologized after a deputy was caught smearing mud on a security camera at a local home. Deputies had gone to the home after police asked for their help finding a registered sex offender who had failed to check in with those monitoring him. As they were leaving, one deputy turned back around and placed mud on the camera lens. The owner of the home, Ashley Mathis, said she did not accept the apology. She said the man they were looking for is her ex-husband, who hasn't lived at the home in six years. She says law enforcement knows that.
