Updated 10:00 p.m. ET: In a press conference, Massachusetts State Police Colonel Timothy P. Alben says “We’re exhausted … but we have a victory.”

Updated 9:10 p.m. ET: Confirmation of capture was followed by applause in the neighborhood of Watertown and a tweet sent out from the Boston Police Department: “In our time of rejoicing, let us not forget the families of Martin Richard, Lingzi Lu, Krystle Campbell and Officer Sean Collier.” Richard, Lu and Campbell were the three killed in the marathon bombings and Collier was the MIT officer shot late Thursday.

Updated 5:40 p.m. ET: Outside of Watertown, Massachusetts State Police recovered “homemade explosives, including pipe bombs and another pressure cooker, as well as more than 200 spent rounds,” reports WBUR — Boston’s NPR station.

Updated 4:37 p.m. ET: Earlier this afternoon, we spoke to Bob Russo, Portland Boxing Club owner, who coached Tamerlan at the Golden Gloves amateur nationals in 2009. Russo said he didn’t know the young boxer very well, but said he was very quite and “a very good athlete.”

Updated 4:25 p.m. ET: While police initially said the brothers robbed a 7-Eleven convenience store in Cambridge near the MIT campus Thursday night, they say now the robbery there was committed by someone else, according to the latest AP report. A surveillance photo they released came from a gas station where the suspects stopped.

Updated 4:10 p.m. ET: “Convince me,” implored Maret Tsarnaeva, aunt of the Boston bombing suspects Tamerlan and Dzhokhar Tsarnaev, in a press conference shot by ABC.

“Why doesn’t the FBI give me more?” she asked, saying she doesn’t have enough information to convince her that her nephews are responsible for Monday’s attack that killed three and wounded 170.

Tsarnaeva, who lives in Toronto, called the FBI’s tip line, saying she believes her nephews are innocent. “They are just normal young men … athletic and smart.”

Updated 3:45 p.m. ET:With Beantown in effect paralyzed as authorities continue their search for a suspect, the Boston Red Sox and Bruins postpone their games Friday night.

Updated 12:38 p.m. ET: Teen Suspect in Boston Bombings a ‘Regular American Kid’

Updated, 12:06 p.m. ET: The uncle of Dzhokhar Tsarnaev, the Boston Marathon bombing suspect still at large, has urged his nephew to turn himself in. Ruslan Tsarni of Montgomery Village, Md., spoke to reporters from his driveway Friday.

“Dzhokhar, if you are alive, turn yourself in and ask for forgiveness,” Tsarni said.

Tsarni said that Tsarnaev and his brother, Tamerlan Tsarnaev, who was killed overnight, were born in Kyrgyzstan. NPR’s Pam Fessler reported that the two suspects are ethnic Chechens from Kyrgyzstan, and the suspect’s aunt told @nprnews that their family was deported to Kyrgyzstan in the early 1990s from Chechnya.

Tsarni said he hasn’t seen them since December 2005 and did not know of any possible involvement in terrorist groups or whether either had any paramilitary training. He added that his family is ashamed and that he loves and respects the United States.

Updated 11:43 a.m. ET: The name and a photo of the MIT police officer killed Thursday night have been released. Authorities say 26-year-old Sean Collier was shot and killed by the Boston Marathon bombing suspects. MIT says Collier was a Wilmington native and Somerville resident who had worked at MIT since January 2012. Before that, he was a civilian employee of the Somerville Police Department. Collier was found shot several times in his vehicle at about 10:30 p.m. Thursday.

Boston Police Commissioner Ed Davis urged all residents to stay at home as the police conduct a door-to-door search for the remaining suspect and any other possible accomplices. Colonel of the Massachusetts State Police Timothy Alben said Watertown was the priority neighborhood for the search.

The suspected bombers robbed a 7-11 store in Cambridge Thursday evening. Shortly afterward, they shot and killed a Massachusetts Institute of Technology security officer, before carjacking a Mercedes SUV and then leading police on a chase through Boston suburbs.
