WATERTOWN, Mass. (AP) — With the city virtually paralyzed, thousands of officers with rifles and armored vehicles swarmed the streets in and around Boston on Friday, hunting for a 19-year-old college student wanted in the Boston Marathon bombing after his older brother and alleged accomplice was killed in a furious getaway attempt overnight.

"This Is What Cops Do"

During the long night of violence, the brothers killed an MIT police officer, severely wounded another lawman and hurled explosives at police in a car chase and gun battle.
The suspects were identified by law enforcement officials and family members as Dzhokhar and Tamerlan Tsarnaev, ethnic Chechen brothers who had lived in Dagestan, which neighbors Chechnya in southern Russia. They had been in the U.S. for about a decade, an uncle said. Their last known address was in Cambridge, Mass.
Tamerlan Tsarnaev, a 26-year-old who had been known to the FBI as Suspect No. 1 and was seen in surveillance footage in a black baseball cap, was killed overnight, officials said. His brother, a 19-year-old college student who was dubbed Suspect No. 2 and was seen wearing a white, backward baseball cap in the images from Monday's deadly bombing at the marathon finish line — escaped.
Their uncle in Maryland, Ruslan Tsarni, pleaded on live television: "Dzhokhar, if you are alive, turn yourself in and ask for forgiveness."
Authorities in Boston suspended all mass transit and warned close to 1 million people in the entire city and some of its suburbs to stay indoors as the hunt for Suspect No. 2 went on. Businesses were asked not to open. People waiting at bus and subway stops were told to go home.
From Watertown to Cambridge, police SWAT teams, sharpshooters and FBI agents surrounded various buildings as police helicopters buzzed overhead and armored vehicles rumbled through the streets. Authorities also searched trains.
"We believe this man to be a terrorist," said Boston Police Commissioner Ed Davis. "We believe this to be a man who's come here to kill people."
The bombings on Monday killed three people and wounded more than 180 others, tearing off limbs in a spray of shrapnel and instantly raising the specter of another terrorist attack on U.S. soil.
Chechnya is the home of an Islamic insurgency that has carried out deadly bombings in Russia and the region, but its militants have never been known to export violence to the West.
Investigators in the Boston case have shed no light on the motive for the bombing and have said it is unclear whether it was the work of domestic or international terrorists or someone else entirely with an unknown agenda.
As officers fanned out across the Boston area, Bryce Acosta, 24, came out of his Cambridge home with his hands up.
"I had like 30 FBI guys come storm my house with assault rifles," he said. They yelled, "Is anybody in there?" and began searching his house and an adjacent shed, leaving after about 10 minutes.
The endgame — at least for Suspect No. 1 — came just hours after the FBI released photos and video of the two young men at the finish line and appealed to the public for help in identifying and capturing them.
State Police spokesman Dave Procopio said police realized they were dealing with the bombing suspects based on what the two men told a carjacking victim during their getaway attempt overnight.
Tsarni, the men's uncle, told The Associated Press that the brothers traveled here together from Russia. He called his nephews "losers" and said they had struggled to settle themselves in the U.S. and ended up "thereby just hating everyone."
Tamerlan Tsarnaev had studied accounting as a part-time student at Bunker Hill Community College in Boston for three semesters from 2006 to 2008, the school said. U.S. government officials, speaking on condition of anonymity because they were not allowed to talk about an investigation in progress, said that he Tsarnaev traveled to Russia last year and returned to the U.S. six months later.
Dzhokhar Tsarnaev was registered as a student at the University of Massachusetts Dartmouth, the school said. The campus closed down along with colleges around the Boston area as the search unfolded.
Their father, Anzor Tsarnaev, said in a telephone interview with The Associated Press from the Russian city of Makhachkala that his younger son, Dzhokhar, is "a true angel." He said his son was studying medicine.
"He is such an intelligent boy. We expected him to come on holidays here," the father said.
