Gunman fired 30 times before killing self

CHICAGO — Moments before her ex-fiance fatally shot her in the parking lot of the hospital where she worked, a Chicago doctor called 911 to report that she had spotted the man and feared for her life. As investigators tried to piece together the events that ended with the deaths of the doctor, a police officer, a hospital employee and the gunman, they were able to fill in details about the attack Monday at Mercy Hospital on the city’s South Side. Dr. Tamara O’Neal had recently called off her engagement to Juan Lopez so when she saw him, she called for help. She also told an acquaintance she was afraid before that person called 911 as well. The former couple argued and Lopez demanded that she return the engagement ring. Then, police said, people inside and around the hospital heard gunfire. Witness James Gray looked out of the hospital window to see where the gunshots had come from and watched as Lopez “stood over her and shot her three more times,” he told reporters. As a squad car pulled up, Lopez turned his handgun on police, striking the vehicle multiple times before he ran into the hospital. Once inside, he kept firing at officers and at one point turned and fired at Dayna Less, a pharmacy resident, when the doors of the elevator she was on opened. Officer Samuel Jimenez was struck in the neck and soon died. During the exchange of gunfire, Lopez was shot once in the abdomen. It was then that Lopez, who fired a total of more than 30 shots and had reloaded his weapon, put the gun to his head and killed himself, police said.
