One week after asking Catoosa County sheriff Gary Sisk to bring in the Georgia Bureau of Investigation to evaluate his office, Ringgold defense attorney McCracken Poston has now extended a similar request to the Fort Oglethorpe Police Department, with hopes of determining whether an FBI agent abused his power by coaxing local officers into looking the other way after pulling him over during possible DUIs.

On Feb. 15, then-Ringgold police sergeant Tom Evans was fired from his department after an internal investigation revealed he did not arrest, did not report, and instead taxied FBI agent Ken Hillman and two women to Chattanooga after employees of a local restaurant called police saying the trio was intoxicated and attempting to drive away on Oct 24.

Following Ringgold Police Department’s investigation, it was discovered that similar incidents might have taken place over the course of the past year and a half involving deputies with the Catoosa County Sheriff’s Office, which prompted Poston’s request to Sisk on Feb. 22.

Thursday afternoon, Poston sent a similar letter to Fort Oglethorpe police chief David Eubanks requesting that he too invite the GBI question police officer Greg Cross, a former Catoosa sheriff’s deputy, who he claims may have been one of two deputies that gave special treatment to Hillman, similar to the actions that cost Evans his job with Ringgold Police Department.

Poston said he asked for and was denied an affidavit from officer Cross recounting an alleged incident, but that Cross did admit to chief Eubanks in detail that an incident did occur.

“All my information is through chief Eubanks, who interviewed officer Cross when I was asking for an affidavit,” Poston said.

“It’s my understanding that somewhere around 3 a.m. on one morning, during your officer’s employment with the Catoosa County Sheriff’s Office, that then deputy Cross encountered Agent Hillman by first observing him operating a motor vehicle in Catoosa County which to Cross appeared to have been involved in a recent accident,” Poston wrote in his letter to Eubanks.

Cross admitted to Eubanks that he pulled over Hillman and that the bumper of his vehicle was almost dragging the ground after an apparent wreck, but that he didn’t arrest him.

Cross also stated that Hillman placed a call to a Catoosa County detective, who came to the scene and gave Hillman a ride home.

“I am disappointed that officer Cross has chosen the path of continuing to conceal and deny revelation of the incident that he was involved with, which is a specific incident regarding a federal agent. I am requesting that you conduct an inquiry into the issue of whether your officer, or anyone else in law enforcement, willfully concealed, failed to investigate or report a motor vehicle accident and DUI.”

Hillman, who is being investigated by the FBI for his actions, has been head of the Northwest Georgia Crimes Against Children Task Force for the past few years.

The task force consists of undercover officers who communicate with people online through chat rooms and ads looking to weed out those looking arrange meetings for underage sex.

The FBI has declined to comment on the matter. “Per policy, the FBI does not comment on personnel matters,” special agent Stephen Emmett, a spokesman for the FBI’s field office in Atlanta, said Thursday.

“I am requesting that you allow the sun to finally shine into this very dark corner of new public concern, and to invite the Georgia Bureau of Investigation to conduct an investigation with officer Cross regarding his actions,” Poston wrote in his letter.
