MAYNARDVILLE (WATE) - Documents with a search warrant show investigators were looking for video evidence and guns late Wednesday when they searched the home of a Knox County school security officer.
The Union County Sheriff's Office investigators were collecting the evidence to build their case in the shooting death of Michael Woodby.
Woodby, 45, was gunned down Monday night outside his home in the 500 block of Highway 370. His body was found in a ditch along the highway.
Security officer Kevin Lee Waggoner, 42, is charged with criminal homicide in the shooting death.
Authorities say the two were arguing when Woodby was shot.
Waggoner's son, Kolton Waggoner, was also at the scene at the time of the shooting. He has not been charged.
The Waggoner and Woodby families had an ongoing feud for nearly three years, which is well documented in court filings and 911 calls.
On the Friday before the shooting, Kevin Waggoner sent a DVD and letter to local news media, including 6 News, and state and local law enforcement agencies. Waggoner says in the letter he wanted to show Woodby and his family "perpetrate crimes against us and then they call the police and lie."
Investigators executed the search warrant to see if additional video footage exists.
The search warrant, filed in court Thursday, shows that Union County Sheriff's Detective Steve Rouse and other investigators removed Glock and Ruger 9mm handguns, ammunition, a laptop, several video tapes, and other equipment and storage devices.
The items were turned over to the Tennessee Bureau of Investigation.
