Vignola worked with Gladstone from 2012 to 2017, and Hankard also worked with Gladstone prior to his second retirement. Guinn, meanwhile, was listed in the original investigative file as one of the officers who responded to the scene in 2014 after Simon was struck. Guinn has previously been invoked in prior allegations against Jenkins, and later identified in unsealed documents as a whistleblower who had flagged the FBI to two officers eventually convicted in the Gun Trace Task Force case.
