The Investigators: Looking into the background of Kenneth Gleason

BATON ROUGE, La. -- (WAFB) -- Kenneth Gleason, 23, is an Eagle scout, born and raised in Baton Rouge. He seemed to have a bright future ahead as he graduated with honors from high school, but not long after that, a check of his history shows trouble started brewing.

Police say the gun Gleason bought the gun he allegedly used in the killings of two men and to shoot at a home last year at a store in Baton Rouge. Officials say the same 9mm gun was used at all three scenes, but the ammo was different each time.

"Three different types of ammo, browning ammunition that was bought when he bought the weapon. The second was federal ammunition, which was found on Florida and Acadian and the third was Magtech that was found on Alaska. Obviously, three different types of shell casings that were found at three different scenes," said East Baton Rouge District Attorney Hillar Moore.
