What the citizen reported

The complaint form places the reported conduct on Interstate 75 northbound around the Atlanta airport. The complainant wrote that the Catoosa County patrol car was traveling over 90 mph in a 65 mph zone and using the HOV lane without anyone else visible in the vehicle. The complainant identified speeding and unlawful HOV-lane use as the alleged wrongdoing.

LaMountain’s response

In his written response, LaMountain said he was returning to Catoosa County after transporting two inmates to south Georgia earlier in the day. He acknowledged using the HOV lane on occasion and wrote that he was unaware of his speed at certain periods while traveling northbound on I-75.

That response matters because the internal review did not simply adopt the complainant’s account. Investigators compared the allegation with body-camera material and vehicle-location data before reaching a finding.

The internal review documented an AVL reading of 92 mph in a 70 mph zone.

Catoosa County Sheriff’s Office disciplinary narrative, September 2025

What the agency says the evidence showed

The investigative narrative states that Lt. Rodney Guffey reviewed LaMountain’s body-camera recording from September 3, 2025. According to that narrative, the recording did not establish his speed or lane while traveling through Atlanta, but it did show a cellphone on the dashboard playing videos. The narrative characterized that as distracted driving.

The same review says an AVL record pulled from the body-worn-camera system showed LaMountain later driving 92 mph in a 70 mph zone on I-75 northbound in Ringgold. The investigator concluded that the documented traffic conduct conflicted with the agency’s Conduct Section III.B.1 concerning violations of law.

The outcome: sustained in part

The complaint disposition was marked sustained in part, meaning the agency determined that an employee committed part of the alleged misconduct. The disciplinary notice dated September 8, 2025 identifies LaMountain as a Deputy Sheriff assigned to Court Services. It states that adverse action was not recommended and records the corrective action as counseling plus two days during which he could not take his patrol car home.

One more useful detail from the open-records response

When the disciplinary file was produced, Captain Coby Cunningham wrote that this was the only disciplinary matter for LaMountain during the previous 12 months. That does not establish his entire career history; it defines only the one-year window requested and produced in September 2025.

Catoosa County: a small county on a very busy corridor

Catoosa County sits in northwest Georgia along the Tennessee line and promotes itself as the “Gateway to Georgia.” The U.S. Census Bureau estimated its population at 69,628 on July 1, 2025, up from 67,872 in the 2020 Census. Ringgold, the county seat and the location referenced in the AVL finding, had 3,414 residents in the 2020 Census and about 4.9 square miles of land.

Those numbers help explain the setting. This is not a huge metro sheriff’s office, but its deputies operate along Interstate 75, one of the major north-south routes between northwest Georgia, Chattanooga and metro Atlanta. A traffic-conduct complaint involving a marked patrol vehicle therefore carries significance well beyond a neighborhood street.

What accountability looks like in a case like this

The public-interest question is not whether every driving complaint should end a deputy’s career. It is whether a complaint is documented, evidence is preserved, supervisors compare the allegation against available technology, the agency states what it found, and the discipline is recorded in a way the public can later examine.

Here, the records show a citizen complaint, an employee response, body-camera review, vehicle-location data, a sustained-in-part finding and documented corrective action. That chain of records is exactly why public-records access matters.

Questions worth asking next

• Was any traffic citation issued in connection with the 92 mph AVL reading?
• Did the agency review additional GPS or AVL data from the Atlanta portion of the trip?
• What policy governs video playback or phone use in moving patrol vehicles?
• What are the agency’s rules for HOV-lane use by marked patrol vehicles when not responding to an emergency?
• When did LaMountain’s promotion to Corporal occur relative to this September 2025 discipline?
