Cobin Burrell, a 31-year-old Johns Hopkins Hospital worker, had the task of cleaning blood from Room 873, where a man killed his ailing mother, then himself after shooting a doctor.

The assignment didn't bother him. "I've seen it on the street a lot of times," the Baltimore resident said.

Burrell and thousands of Hopkins doctors, nurses, technicians and patients resumed their routines Friday, a day after Paul Warren Pardus of Arlington, Va., triggered a standoff after he became distraught over the care given to his 84-year-old mother, pulled out a gun and began shooting. The doctor, orthopedic surgeon David B. Cohen, was in fair condition after surgery.

Staffers and visitors expressed confidence in the way police and security handled the incident, even if some questioned how a man with a weapon got on a patient floor so easily.

"I think security did a good job," said Andrew Roquiz, a visiting fourth-year medical student from Loma Linda University in California. "The Baltimore police contained the situation. There wasn't any panic."

The eighth floor of Hopkins' Nelson Building reopened late Friday afternoon, and the facility where transplant patients receive treatment and therapy seemed back to normal. Visitors could easily enter hallways that a day earlier had been filled with heavily armed tactical officers.

The room where Jean Davis had been recovering from surgery when she was shot by her son was empty. Other patients who had been moved off the floor during Thursday's incident appeared to be back in their rooms.

The Hopkins campus is a virtual city within a city — an estimated 80,000 workers and visitors pass through each week — and is guarded by teams of private security guards and uniformed city police officers.

"Hospitals are and must remain places of hope and healing that are open to the public," Hopkins officials said in a statement Friday. "They cannot be turned into armed citadels. Johns Hopkins never closes. Our doctors, nurses and staff took care of our very sick patients even during the crisis."

Roquiz, 27, was doing rounds on the sixth floor of an adjacent building when the shootings occurred. He said he and an attending physician went to a workroom where they stayed until given the all-clear.

Roquiz, who started at Hopkins on Monday, said he had been warned about safety in Baltimore — the hospital campus is in one of the city's most dangerous neighborhoods — but was not prepared for what happened Thursday.

"It's odd how, in a hospital where we're trying to save a life, someone comes in and tries to take a life," he said.

Michael Clark, 51, was waiting Friday for a ride in front of the Nelson Building. He was wearing a bright-blue Nike shirt with the breast cancer ribbon symbol, his medical bracelet and a yellow Livestrong band. He comes to Hopkins each month from his home in Prince George's County for treatment for diabetes and failing kidneys, and is on a waiting list for a transplant.

He saw news coverage of the shooting, but it didn't stop him from coming to Baltimore. "I wasn't concerned," he said. "I feel pretty relaxed, confident."

Michelle Hunter, 23, of Churchville arrived at the hospital Thursday night after a 90-minute ride in an ambulance with her 2-year-old daughter, Zoe Aguilar-Rodriguez, who suffered a concussion after a fall. Hunter said she wasn't worried about the violence.

"They had it contained," she said, making "everyone in the hospital feel safe."

But Jeffery Herriott, whose 15-year-old sister was a patient on the third floor of the Nelson Building when the shooting occurred, was a bit more concerned. The 18-year-old, visiting with his mother, noted that anyone could walk into the building.

Hopkins officials use magnetometer "wands" to check visitors during high-risk situations, but only in the emergency room on East Monument Street, where gunshot victims are routinely treated and rival gang members can show up as patients or visitors.

Still, officials "will continue as always to assess and reassess our security needs," the hospital statement said.
