Mercy Hospital has identified two members of its staff killed in a shooting that left four dead, also including the gunman and a police officer.
Emergency room physician, 38-year-old Dr. Tamera O'Neal, was described as a fascinating, hardworking person. Hospital officials said that O'Neal never worked on Sunday because of her religious beliefs.
Police say O'Neal was confronted in the hospital parking lot by the gunman, with whom she had been in a domestic relationship. Witnesses say the man shot her and she fell to the ground. The gunman then stood over her and shot her again.
Hospital officials say 25-year-old pharmaceutical assistant Dayna Less, who was in training to become a pharmacist, was also killed. According to police Superintendent Eddie Johnson, the woman was shot as she stepped from an elevator. She was a recent Purdue University graduate.
Also killed was 28-year-old Chicago Police Officer Samuel Jimenez, the father of three children.
