Gary Clark

Gary Clark is a grieving widower whose wife Allison was taken off life support at Seattle Grace Hospital after being declared brain dead. Mr. Clark, grieving heavily, proceeded to stage a hospital shooting. He killed Dr. Charles Percy, a nurse, Dr. Reed Adamson, and 8 other people. He also shot Doctors Alex Karev, Owen Hunt and Derek Shepherd. He caused Meredith to miscarry due to the stress of seeing Derek shot in the chest, with the bullet going straight through his heart, and she miscarried while checking Owen to see if his wound was only superficial. He shot at Lexie Grey, but missed because a SWAT member who was searching the hospital for survivors shot him in the shoulder. He walked into where Dr. Robbins and Dr. Torres moved all the pediatrics patients, but Callie made him move on by giving him bandages and instructing him how to use them to stop the bleeding.
