CHICAGO (WBBM NEWSRADIO) -- Four people -- a Chicago Police officer, a doctor, a pharmacy resident, and a suspected gunman -- were killed Monday in a shooting and exchange of gunfire at Chicago’s Mercy Hospital in the South Side Bronzeville neighborhood.

Chicago Police Supt. Eddie Johnson said the incident began around 3:30 p.m. outside the hospital in the 2500 block of South Michigan Avenue as a man argued with a hospital employee he’d been involved with. When a third person tried to intervene, the man lifted his shirt to display a handgun, and the person ran into the hospital to call 9-1-1, Johnson said.

The shooter had a prior relationship with the woman, who worked at the hospital, Johnson said.

Shots were fired, and Chicago police officers began arriving, Johnson said. The gunman fired at officers and ran into the hospital, where he exchanged gunfire with police and SWAT members who pursued him. Inside, the offender shot a female hospital staffer and mortally wounded Police Officer Samuel Jimenez before the gunman himself was fatally shot, the superintendent said.

Jimenez was rushed to University of Chicago Medical Center, where he was later pronounced dead, authorities said.

The doctor was identified as 38-year-old Tamara O’Neal, an emergency medicine physician. She grew up in Portage, Ind. and was a resident of La Porte.

The other employee was Dayna Less, a 25-year-old, first-year pharmacy resident who was a recent graduate of Purdue University. She lived in the West Town neighborhood.

The shooter was identified as Juan Lopez, 32, of the North Park neighborhood, according to a police source and the Cook County medical examiner’s office. Additional information about Lopez was not released.

Lopez was found dead after suffering a gunshot wound. It was not immediately clear if he was shot by police or if he turned his gun on himself. He was pronounced dead at the scene, according to the Fire Media Affairs.

Jimenez was a 2nd District officer who was on another call with his partner when they received directions to assist officers at Mercy Hospital, Johnson said. They were undeterred by the sound of gunshots.

“They did what heroic officers always do – they ran toward that sound of gunfire,” Johnson said at a news conference Monday evening.

Mayor Emanuel and Johnson met with the officer’s family before the announcement was made that all four shooting victims were dead. Jiminez was rushed to the University of Chicago Medical Center, where he died.

“The [Fraternal Order of Police> asks that everyone keep the young officer who gave his life today to protect the public in their thoughts and prayers,” said Martin Preib, spokesman for the union that represents the city’s officers.

One of the women was also taken to U of C and the other woman was taken to Northwestern Memorial Hospital.

“This tears at the soul of our city,” Mayor Rahm Emanuel said. “It is the face and the consequence of evil.”
