Boston police: 3 more marathon bombing suspects in custody

(RNN) - Boston police reported Wednesday three additional suspects in the marathon bombing have been taken into custody, according to the department's official Twitter feed.

CNN reported the suspects were two students from Kazakhstan and a U.S. citizen, and they would be charged with obstruction of justice and making false statements to authorities. It also stated Katie Russell, Tamerlan Tsarnaev's widow, was not one of the three.

They are scheduled to appear at a federal courthouse Wednesday.

The tweet from Boston PD stated more details would be following. Another tweet stated there was no threat to the public.

Police believe brothers Dzhokhar and Tamerlan Tsarnaev dropped pressure cooker bombs at the Boston Marathon on April 15, Patriots Day, then shot and killed a Massachusetts Institute of Technology police officer a few days later.

The FBI previously searched the parent's home of Russell, located in North Kingstown, RI.

Russell has been staying there since her husband was identified as a suspect. Her lawyer, Amato A. DeLuca, said she has been cooperating with FBI investigators.

Law enforcement officials discovered female DNA on a piece of one of the pressure cooker bombs, according to CNN, but it is unclear if it is tied to any suspects.

Investigators said the DNA could be from anyone, including a clerk who sold them the item.

The FBI removed bags of evidence from Russell's home, including one labeled "DNA samples."

The bombing at the finish line of running's biggest annual race killed three people and injured more than 260. Tamerlan Tsarnaev was killed during a getaway attempt April 18 and 19; Dzhokhar Tsarnaev was injured but captured alive by authorities.

Officials said after the Boston bombings, the brothers were planning to detonate multiple explosives in New York City.

"We were informed by the FBI that the surviving attacker revealed that New York City was next on their list of targets," New York Mayor Michael Bloomberg said. "He told the FBI that he and his brother intended to drive to New York to detonate explosives in Times Square."

On April 19, the two brothers shot MIT police officer Sean Collier. The shooting began a chase and shootout that spanned hours and ended in the death of the older brother.

Dzhokhar Tsarnaev got away after the first gunfight when he backed the stolen vehicle over his brother before running away. Tamerlan Tsarnaev was in cardiac arrest by the time authorities got him to the Beth Israel Hospital emergency room; doctors soon pronounced him dead.

Two years ago, Tamerlan Tsarnaev was interviewed by the FBI at the request of a foreign government the Bureau would not identify. Though no incriminating evidence came from the interview, their mother, Zubeidat Tsarnaeva, said her older son was "persecuted" by the FBI.

As they mounted the unprecedented manhunt, officials shut down all of Boston, Watertown and the surrounding area while they went door-to-door looking for the surviving suspect.

They were afraid the remaining suspect might have on an explosive vest - his brother had explosives strapped to his body when he died. CNN also reported police found homemade explosives during searches Friday, and experts performed controlled detonations throughout the day.
