U.S. Attorney: 'Tonight We Can Sleep A Bit Easier'

BOSTON (CBS) - Gov. Deval Patrick and Mayor Tom Menino said the people of Boston will sleep easier tonight after the capture of Boston Marathon bombings suspect Dzhokhar Tsarnaev Friday night.

"All law enforcement worked so well and so hard together to bring us to tonight's conclusion," Patrick said at a press conference shortly after Tsarnaev's capture in a Watertown backyard.

The arrest marked the end of a tumultuous week and capped off a violent manhunt which started Thursday night with the murder of MIT Police Officer Sean Collier, 26, of Somerville.

"Thank you, thank you, thank you," Menino said as he addressed crowds gathered.

Officials thanked the public for their cooperation and patience during the past week but said there is still work to be done.

During the manhunt people in many communities around Boston, including Watertown were ordered to stay in their homes. The MBTA was shut down as police hunted for Tsarnaev.

"We feel a tremendous sense of gratitude and relief," U.S. Attorney Carmen Ortiz said. "Tonight there is closure but for me the journey continues. This will continue to be an ongoing investigation and an active investigation."

Ortiz noted the amount of evidence law enforcement officials will continue to collect and evaluate before charges can be filed.

"There are still some questions remaining to be answered," she said.

Davis Speaks After Arrest

Boston Police Commissioner Ed Davis said Tsarnaev's arrest brings closure after Monday's brutal attack on the Boston Marathon finish line.

"As part of the investigation, I got to see how brutal that attack was over and over again but more importantly, I got to see what Boston Police and first responders did to put people back together," Davis said. "There are the kind of things that came out. It makes me proud to be a Boston Police officer and proud to be part of this team."
