These Are the Victims of the Chicago Mercy Hospital Shooting
A police officer, a doctor and a recently graduated pharmacist were the three victims in a shooting at Chicago Mercy Hospital on Monday, authorities have confirmed, not including the gunman. The shooter was seen in a hospital parking lot arguing with Dr. Tamera O'Neal, 38, with whom he had previously been in a domestic relationship, Chicago Police Superintendent Eddie T. Johnson told reporters Monday. The gunman then shot and killed O'Neal and fled into the hospital when police officers arrived at the scene. Inside, he fatally wounded 25-year-old pharmacy resident Dayna Less and 28-year-old Police Officer Samuel Jimenez. Johnson said the gunman, who has not yet been identified by police, was also killed in an exchange of gunfire inside the hospital. However, it remains "unclear right now whether it was by police gunfire or if it was a self-inflected wound," he added. Here's what to know about the victims of the Chicago shooting.
