BOSTON (NBC) -- One week after an annual springtime rite in Boston was shattered by a pair of explosions that killed three people and injured more than 170, including some who lost legs, shock and fear gave way to grief and healing as memorials were scheduled to remember those lost.

Gov. Deval Patrick, Mayor Thomas Menino, and charitable organization One Fund Boston called for a minute of silence in Boston and across the Commonwealth at 2:50 p.m. on Monday. The White House announced that President Obama would observe the minute of silence as well.

A funeral was planned in Medford, Mass., for Krystle Campbell, 29 on Monday morning. On Sunday, a wake was held for the restaurant manager, and lines stretched out the door and down the street from a funeral home. The memorial, which was scheduled to last an hour, went on for five, WHDH reported.

Gov. Patrick planned to attend Campbell's funeral on Monday.

Medford draped a 45-by-90-foot American flag across the front of city hall on Monday morning in honor of Campbell and the other victims.

At Boston University, where Chinese graduate student Lingzi Lu, 23, was working toward a master's degree in statistics before being killed in the explosions near the marathon finish line, a public memorial was planned for 7 p.m. Monday night.

A memorial scholarship has been instituted in Lu's memory.

"There isn't an individual at BU who didn't have some connection to people who were there," university trustee Kenneth Feld said in a release from the school.

Over the weekend, more balloons and teddy bears were added to a makeshift memorial for 8-year-old Martin Richard of Dorchester, who died last Monday as well. His mother Denise and sister Jane, 7, were wounded in the blast; Denise required brain surgery and Jane lost a leg to the pressure-cooker bombs set off on the race sidelines.

The Richard family thanked law enforcement for "a job well done" in a statement released after the capture of bombing suspect Dzhokhar Tsarnaev.

Mayor Menino planned to observe Monday's minute of silence in Peabody Square in Dorchester.

Richard was remembered at a packed mass on Sunday at the family's St. Ann Parish in Dorchester, where neighbors have said his parents are active community members.

"Our entire community shares the grief and suffering felt by our young family," the parish's Father Sean Connor said in a letter on the church's website. "We can only imagine the suffering that the Richard family carries today, as a result of the Boston Marathon tragedy, will be with them each day of their lives."

The Massachusetts Institute of Technology mourned the loss of a popular campus safety officer who only got to enjoy a little more than a year on the job. Officer Sean Collier was shot and killed by the suspected bombers late on Thursday night, police said. The men shot the 26-year-old Collier multiple times while he was sitting in his vehicle, according to authorities.

A memorial service for Collier has been planned for Wednesday, April 24, at noon, according to a release from MIT police. Collier's family has requested that his wake and funeral services remain private.

The proceeds from a Brahms performance at MIT on Sunday that drew hundreds of singers from local choruses were donated to One Fund Boston. 

On Monday, the areas where the blasts occurred were transitioning from crime scene to street scene. Mementos left at a makeshift memorial on Boylston Street are being moved to a park at nearby Copley Square; city workers on Sunday began removing the running shoes, flowers, and notes left by friends, family, and strangers with the goal of having all pieces of the memorial moved by the end of the week.

Students and faculty at the University of Massachusetts at Dartmouth, where alleged bomber and Suspect 2 Dzhokhar Tsarnaev was enrolled as a sophomore, planned to observe the minute of silence. A student vigil on campus was planned for 5 p.m.

The mayor's office released a five-step plan on Sunday to reopen the area around the finish line on Boylston Street that included testing buildings near the blast sites and removing debris.

"Nearly a week ago our city took a deep breath and was forced to dive into a pool of uncertainty and fear," Menino said in a press release on Sunday. "Friday as our officers reported to the world ‘we got him,' a huge sigh of relief was felt across our great city and nation so now it is time for us to start moving our city forward."
