Several dozen people injured in the Boston Marathon blast remain hospitalized, including a 7-year-old girl who is in critical condition with "multiple leg injuries" as the city observed a moment of silence for the bombing victims.
The update on the injured was released as services began for the three people who in died in last Monday's bombing.
Krystle Campbell, 29, was laid to rest today at a private ceremony at St. Joseph's Church in Medford, Mass.
There was concern members of the Westboro Baptist Church, known for their hate speech, would picket the funeral, but the Teamsters Local 25 stepped in to make sure Campbell's family would be shielded.
"We had the place pretty much locked down," Local 25 President Sean O'Brien told ABCNews.com. "There is no place for anybody that was going to disrupt someone's funeral."
O'Brien estimated 1,000 Teamsters stood outside the church, ready to take care of business in the event there was a problem. It's not clear if any protesters showed up.
The parents of Lingzi Lu, the Chinese graduate student killed in the bombing, will attend a memorial service tonight at Boston University before they return home to China with the body of their daughter, a university spokesman told ABCNews.com.
Lu's parents departed for the United States on Friday to pick up their daughter's remains, China's official Xinhua news agency reported. Lu was the only child in a family adhering to China's one-child policy.
At least $560,000 has been committed to a scholarship fund established in Lu's name, according to the university.
It's not clear yet when the funeral for the third bombing victim, 8-year-old Martin Richard, will be held. The boy's family is also coping with injuries to his 7-year-old sister, Jane, who lost a leg in the blast, and the boy's mother, Denise, was also gravely injured.
The Children's Hospital of Boston declined to identify the 7-year-old girl they said was still in critical condition, and the Richard family declined to comment.
The bombing killed three and injured at least 170 people. Of the injured, 48 remained hospitalized, and two were in critical condition, according to an ABC News count. The identity of the second victim in critical condition was not known.
Among those still in the hospital were Erika Brannock and her sister, Nicole Gross. Gross' brother-in-law told ABC News last week that doctors had to amputate below Brannock's knee. He said Gross, his sister-in-law, was undergoing a series of surgeries as pins hold the bones together in one of her legs.
The family did not disclose where Gross and Brannock were being treated.
A moment of silence was observed today at 2:50 pm EST, marking exactly one week to the minute when the first bomb detonated, to honor the victims of the attack. It was followed by the sound of bells.
Doctors said some of their most critical patients had sustained lower extremity injuries, include bone and vascular trauma, and some required life-saving amputations.
Dr. Jeffrey Kalish, director of endovascular surgery at Boston Medical Center, said today all of the hospital's amputation patients were "on the road to recovery."
"It takes a lot of work and they have to learn new routines, but we are gearing up for a mass exodus to rehab," he said. "Everything is starting to return to a normal state."
While physical recovery is one hurdle, victims will also have to deal with the mental scars, Terence Keane, a psychiatrist at Boston University School of Medicine said.
"Recovery from this," he said, "psychologically is a marathon."
