Col. Timothy Alben, head of the Massachusetts State Police, said during a Friday afternoon news briefing that the second Boston Marathon bombing suspect — Dzhokhar A. Tsarnaev — had not yet been found despite a massive search in Watertown, but that the hunt for him continued.

“He fled on foot. We do not have an apprehension, but we will have one,” he said. “We are committed to doing that.” He also asked that anyone who might see the suspected bomber, do not try to apprehend him. “Dial 9-1-1,” he said, describing the suspected bomber as “quiet and dangerous.”

He said the younger brother’s ties were in Massachusetts and he believed that he remained in the state. He also said the brothers threw explosives at the police officers during the police chase and shootout.

Massachusetts Gov. Deval Patrick also noted that 200 shots were exchanged in the shooting between the bombers and police.

The father of the two brothers suspected of bombing the Boston Marathon says his sons were framed.

“They were set up, they were set up!” Anzor Tsarnaev said in an interview with The Associated Press. “I saw it on television; they killed my older son Tamerlan.”

Tamerlan Tsarnaev was killed overnight in a shootout with police in Watertown, Mass., after the FBI released photo of him alongside his 19-year-old brother, Dzhokhar, at the site of the bombing on Monday near the finish line of the famous race.

The men are accused of killing at officer at the MIT campus and leading police on a car chase before the standoff.

Dzhokhar Tsarnaev is still at large, prompting authorities to lock down Watertown and ask everyone in Boston to stay indoors.

An aunt of the boys also gave an impromptu interview, aired on CNN, in which she said there was no evidence against her nephews and that the photos must have been staged.

Ethnic Chechens, the Tsarnaevs left the embattled region of southern Russia and moved into neighboring territory in Asian and then to Dagestan, another Muslim republic in Russia, according to multiple media accounts.

Anzor Tsarnaev spoke about his sons from Dagestan, where he now lives.

His comments contrasted those of an uncle in Maryland, Ruslan Tsarni, who said the boys were “losers” and probably had trouble assimilating into American society.

He implored Dzhokhar to turn himself in to authorities and beg for forgiveness.

Zubeidat Tsarnaev, the mother of the two Boston bombing suspects, told Russia Today’s English language TV news channel that her sons were innocent.

“This is a set up,” she said by telephone from Makhachkala, capital of the Russian Republic of Dagestan.

“My sons would never do such a thing,” she said. “Tamarlan, the eldest, had “got involved in … religious politics about five years ago,” but he “never told me he would be on the side of Jihad.” “Nobody talked about terrorism or jihad” in her household, she said.

“The mother’s first name, Zubeidat, suggests she is of Dagestani origin,” noted Mairbek Vatchagaev, a scholar with the Jamestown Foundation, a Washington-based think tank, adding that could account for the family’s decision to move to Dagestan.

He said the family appeared to have moved there after the second Chechen war began in 1999, having apparently become refugees.

Bulger was arrested in June 2011 in a Santa Monica, Calif., home he shared with his girlfriend, ending a manhunt that had landed the infamous mob leader on the FBI’s “Ten Most Wanted List.”

The FBI said Bulger and his longtime companion, Catherine Elizabeth Greig, were taken into custody without incident by agents acting on what the FBI said was a tip resulting from the release of videos and photographs on daytime TV and billboards.

The 81-year-old crime boss was wanted in connection with 19 homicides and also was accused of racketeering, conspiracy to commit murder, conspiracy to commit extortion, narcotics distribution, conspiracy to commit money laundering, extortion and laundering illicit mob profits.

“Recent publicity produced a tip which led agents to Santa Monica where they located both Bulger and Greig,” Mr. DesLauriers, said at the time.

“Of course, we’re ashamed. … They are children of my brother, who had little influence over them,” he said.

However, he repeatedly called them “losers” who may have harbored “hatred to those who were able to settle themselves.”

The elder of the brothers, Tamerlan, was killed in a shootout with police oversight. The younger brother, Dzokhar, is still at large.

“If you’re alive, turn yourself in and ask forgiveness from the victims, from the injured,” the uncle told him.
