Nineteen-year old Billy Jean Tiffey III was caught robbing a house in Tulsa, Oklahoma, when the homeowner arrived. Michael Lish had just entered the back of his house when he heard noise coming from the master bedroom, so he went to check things out. Once Michael neared the bedroom and noticed the thief, Tiffey approached him with a sword he had taken from the house. When Tiffey did not comply with Lish's request to stop approaching him, Lish pulled out his gun and shot him. However, the suspect then pulled a gun of his own. Lish was ready, and shot him two more times, killing him.
Also among the intruder's collection of weapons was a .38 caliber handgun, a 9mm handgun taken from inside the homeowner's house, a stun gun and a knife. Tiffey had also just been released from jail and had a history of drug offenses and driving under the influence.
