A doctor, a pharmacist and a police officer were victims of the Chicago Hospital shooting

O'Neal, 38, was shot in the hospital parking lot immediately after the end of his shift. Police said the shooter had approached her in the parking lot, had quarreled with her and then shot at her.

The gunman was O Neal's fiancé until the end of September, when she canceled the engagement, said her father, Tom O'Neal, at CNN on Tuesday. Lopez "could not accept" that the relationship was over, said his father. The former couple was to be married in October, he added.

Neal's father stated that she was a strong believer and that she and Lopez were not united in this faith.

"I thank God for the 38 years we have spent with her, I thought we would have a lot more time," said Tom O. Neal. "We expected to be grandparents, spoiling the grandchildren.

"She is extremely loved by her family, it is not a loss," he said. "The things she's done, we'll keep them."

O Neal began his career in medicine by helping children in need to procure school supplies. She dedicated herself to the church and agreed to work a large part of the weekend to ensure the Sunday rest, recalled her boss.

"The best person ever, really," said Dr. Patrick Connor, president of the hospital emergency department.

Originally from Portage, Indiana, O. Neal graduated from the Emergency Medicine Program of the University of Illinois-Chicago in 2016, did he declares.

"Simply one of the most fascinating and hardworking people," Connor said. "Medicine was a second career for her, and she started practicing here two years ago."

Officer Samuel Jimenez: "Heroic Actions & # 39;

Samuel Jimenez, the police officer killed, had just become a full member of the force after completing his probation training after he arrived in the department in February 2017, police superintendent Eddie Johnson told reporters.

Jimenez, 28, and her partner went to the hospital when they heard about the distribution of traffic about the shootings.

"They were not assigned to this particular call, but they went there," Johnson said, "because that's what we do."

Jimenez is survived by a wife and three children, Johnson said. The police officers who responded "have saved a lot of lives because we just do not know how much damage he was willing to do," Johnson said.

A procession took place on Monday night and the Chicago police posted on Twitter to pay a final tribute.

"Today, we mourn the Chicago policeman, Samuel Jimenez, whose heroic actions saved countless lives, ran to danger, ran to those shots, and ran into the Altruist ", tweeted the department.

Dayna Less: She was tenacious

Dayna Less, 24, was a first-time pharmacy resident, the hospital learned. She recently graduated from Purdue University and joined the hospital staff in July.

The shooter fired at her as she was coming out of the elevator, Johnson said. She had "nothing to do with anything" related to the shooter.

In adolescence, Less suffered severe headaches that left her in the impossibility of going to school, said her father, Brian Less, at a conference release Tuesday. She finally found a doctor at Georgetown University who performed two surgeries to correct the symptoms, he said.

"I have a picture where she exchanged two black eyes for a smile," he said. "She came out of surgery, she was beaten, but she smiled for the first time in a year."

The experience has made Dayna tenacious in her career and in the way she has been busy with herself, he said.

Brian Less told the story of his daughter's rotation in Kenya as a pharmacy student. Once there, Kenyan doctors went on strike, leaving pharmacists and the other few people with the responsibility of educating patients.

Dayna felt overwhelmed, he said, but she still wrote on her blog about her "wins" of the day and focused on the positive things she's encountered .

"She was a positive person," he said. "It's who she was."

Brian Less said that he did not want his daughter to be remembered as a victim.
