We have new details about the deadly officer-involved shooting in Bluff City over the weekend.

The Sullivan County Sheriff says every time an officer takes a life, it's traumatic for them too. The three officers involved are still on administrative leave, but we spoke with a captain who knows all too well about what they're going through.

Captain Steve Williams fired the first shot at 62 year-old Thomas Cowan, who walked into Sullivan Central High School with two loaded guns in August 2010. Click here to read more.

Cowan died in that incident, and it's something Captain Williams says he thinks about everyday three years later, even after the debriefing process. "I knew I did what I had to do. I'm at peace with it. I'm at peace with God with it because I feel like I saved lives," says Captain Steve Williams.

Sheriff Wayne Anderson says his officers involved in Sunday's incident are doing well. They'll undergo a debriefing session, and will be offered mental health services if necessary.

All three officers are still on administrative leave, which is standard in these types of situations. There's no timetable yet on when they'll be back.

The Tennessee Bureau of Investigation is investigating the shooting.
