On the eve of going to trial for opening fire on two fishermen on Harvest Farms Lake, the defense for Floyd Kirby say the shooting was an accident – not an act of attempted murder as alleged by prosecutors.“This was accidental, period,” said defense attorney Tim Pirtle who will represent Kirby, 76, when his trial begins tomorrow for the shooting of his neighbor, Ken Murray. “My client is a Vietnam veteran and has combat experience so if this had been an intentional plan to kill he would have walked down to the water’s edge instead of firing from more than 100 yards away. The chances of hitting anyone on that boat with a shotgun from that far away were about the same odds of getting hit by lightning.”Murray suffered buckshot wounds to the arm and torso as he and friend Stan Owenby fished in a boat behind Kirby’s house on Harvest Farms Lake.
