Von Miller will not face criminal charges after an investigation by the Parker (Colorado) Police Department earlier this year.

The district attorney's office said the case did not meet the standards of probable cause of admissible evidence "to support a conviction beyond a reasonable doubt, and that the decision to charge is in the interests of justice.''

The office said it would not comment further on an investigation "in which there was never a citation, arrest or filing."

Neither the police nor the district attorney have said what the investigation was for or what charges Miller could have faced.
