Scumbag Bomber Beats Up Women
The slain Boston Marathon bombing suspect should have been deported in 2009, said Chris Farrell with Judicial Watch. Farrell said 26-year-old Tamerlan Tsarnaev was in the United States after being offered asylum but should have been deported after being convicted of domestic violence.
"DHS, did nothing," he said. "Makes no connection between his criminal behavior and his status of trying to gain citizenship here."
The Brothers Tsarnaev
A man identified by several sources as Tamerlan Tsarnaev, 26, died after an overnight shootout with police. He's the man described Thursday by the FBI as black-capped Suspect No. 1 in the attacks Monday that killed three.
His brother, Dzhokar Tsarnaev, apparently escaped -- leading police to throw a huge dragnet around the region. In photos released by the FBI of the bombing suspects, the younger brother is seen wearing a white cap. The agency called him Suspect No. 2.
-- After more than 12 hours of intense operations, police said Friday afternoon that they were continuing to run down new leads and go door-to-door in Watertown, searching for Dzhokar Tsarnaev, said Col. Timothy Alben of the Massachusetts State Police. Bomb techs plan to conduct a controlled blast later in Cambridge, an indication that police found suspected explosives.
-- Dzhokar Tsarnaev became a U.S. citizen on September 11, 2012, the 11th anniversary of the terrorist attacks in New York and Washington, a federal official told CNN's Mike Ahlers.
-- A Maryland man who said he was the suspects' uncle told reporters the two men had brought shame on their family and all ethnic Chechens with the attacks, which he called an atrocity. "If you're alive, turn yourself in and ask for forgiveness," Ruslan Tsarni urged his nephew.
-- A former teacher at the high school Dzhokar Tsarnaev attended, who lives near Tsarnaev's residence now, described the younger brother as "a wonderful kid" who seemed incapable of such violence.
-- Wednesday, two days after the bombings, Dzhokar Tsarnaev apparently tweeted, "I'm a stress free kind of guy." Early Tuesday, he tweeted, "There are people that know the truth but stay silent & there are people that speak the truth but we don't hear them cuz they're the minority."
-- Tamerlan Tsarnaev was wearing explosives and a triggering device when he died, a source briefed on the investigation told CNN's Deborah Feyerick.
Background Details on the Brothers
According to a source briefed on the investigation, the brothers came from the Russian Caucasus and had moved to Kazakhstan at a young age before coming to the United States several years ago.
A statement from the office of Chechnya's president echoed that: "According to preliminary information, coming from the relevant agencies, the Tsarnaev family moved many years ago out of Chechnya to another Russian region," press secretary Alvi Kamirov told Russia's semi-official Interfax news agency. "After that they lived for some time in Kazakhstan, and from there went to the U.S. where the family members received a residence permit. Therefore the individuals concerned did not live as adults in Chechnya."
Two sources told CNN Dzhokar Tsarnaev came to the U.S. as a tourist with his family in the early 2000s and later asked for asylum. He became a naturalized U.S. citizen in 2012. Tamerlan Tsarnaev was not a naturalized citizen, a source said. He came "a few years later" and was lawfully in the United States as a green-card holder.
Tamerlan Tsarnaev had studied at Bunker Hill Community College and wanted to become an engineer, the source said. He then took a year off to train as a boxer.
A posting on a social media site in the elder brother's name included the comments: "I don't have a single American friend. I don't understand them."
Dzhokar Tsarnaev attended Cambridge Rindge & Latin, a public high school, said Eric Mercado, who graduated a year behind the suspect. Mercado said Tsarnaev had worked at Harvard University as a lifeguard.
"We hung out; we partied; we were good high school friends," Mercado told CNN.
"We're all, like, in shock. We don't really understand. There were no telltale signs of any kind of malicious behavior from Dzhokar. It's all coming as a shock, really."
Mercado said he lived a block away from the suspect and did not know his older brother.
Dzhokar Tsarnaev is currently registered as a student at University of Massachusetts Dartmouth, which ordered its campus evacuated on Friday. The school is located 65 miles south of Cambridge, just west of New Bedford.
Larry Aaronson, Dzhokar Tsarnaev's neighbor and a former teacher at the high school Tsarnaev attended, called him a "wonderful kid."
"He was so grateful to be here, he was compassionate, he was caring, he was jovial," Aaronson told CNN.
A Violent Night
The violence began late Thursday with the robbery of a convenience store.
Soon after, in Cambridge, across the Charles River from Boston, Massachusetts Institute of Technology police officer Sean Collier was fatally shot while he sat in his car, the Suffolk County District Attorney's Office said in a statement. Police believe the bombing suspects were responsible for the shooting.
The two suspects, according to authorities, then hijacked a vehicle at gunpoint in Cambridge, telling the driver that they are the marathon bombers, a law enforcement source told CNN's Joe Johns.
At some point, apparently at a gas station, the source said, the driver escaped.
Police, who were tracking the vehicle using its built-in GPS system, picked up the chase in Watertown. The pursuit went into a residential neighborhood, with the suspects throwing explosives at police.
A firefight erupted and ultimately one bomber -- later identified as Tamerlan Tsarnaev -- got out of the car. Police shot him, and his brother ran over him as he drove away, according to the source.
Richard H. Donohue Jr., 33, a three-year veteran of the transit system police force, was shot and wounded in the incident and taken to a hospital, a transit police spokesman said Friday. The officer's condition was not immediately known.
