In 2014, police suspected Guy was selling drugs and obtained a no-knock warrant for his apartment. Around 5:45 a.m. on May 9, a SWAT team shattered Guy’s bedroom window and shoved a battering ram into his front door. Thinking someone was trying to break in to rob or kill him, Guy said he grabbed his gun and fired through the window. Police fired back.
Police say that Guy shot four police officers, including Charles Dinwiddie, a leader of Killeen’s SWAT team who later died from his injuries.
The raid turned up no drugs in Guy’s apartment.
