The Bradley County Sheriff's Office is investigating a complaint that one of its deputies got into a verbal altercation with a 16-year-old student. The alleged incident happened last week at Bradley Central High School.

On Monday, the BCSO launched an internal affairs investigation and suspended Lt. Dennis Goins with pay. Goins has been on the force for 25 years.

Brandy Payne said she was "furious" after her son called and told her what happened at school last Wednesday.

"The Lt. was cussing at my son and threatening him," Payne told Eyewitness News.

According to Payne, the sophomore at BCHS was called into the school resource officer's office, where Goins, who is not the SRO, had some choice words with her 16-year-old.

"He kept saying (my son) better watch it. He's gonna get him," Payne said. "If anything happens to his daughter, whether it's his fault or someone else's fault, he was gonna get him. That he was close to being 18, so there wasn't a lot he could do now. But 18 was coming soon, and he would be waiting for him."

Payne said this all started after her son sent a text message to the deputy's daughter, telling her to stop spreading rumors.

Payne is mad she didn't get a phone call before the confrontation happened.

"He should've had an adult, a guardian, a parent, somebody with him, before the Lt. was ever allowed to question him, threaten him, cuss him, anything," she said.

That's what prompted her to file a formal complaint at the Sheriff's office.

"That's unacceptable," Payne said. "Just because you have a badge, doesn't give you the right to do what you want to do."

Channel 3 reached out to the school, but our phone calls were not returned. Goins will remain on paid leave until the BCSO's IA investigation is complete.
