NEW ALBANY, Ind. (WHAS11) -- Suspected serial killer William Clyde Gibson used to be a military informant.
The Courier Journal is reporting that Gibson used to work as an informant while in the Army and helped set up the arrests of soldiers, a sergeant, and a German civilian who were selling heroin.
Military documents also show that Gibson was court-martialed in 1979 for stealing a Mercedes-Benz, going AWOL four times and escaping from confinement.
In part because of his work as an informant, he was sentenced to only five months at the military prison in Fort Leavenworth, Kansas and given a bad-conduct discharge.
Gibson is from New Albany and has been charged in the murders of three women in Southern Indiana.
