3 new Boston suspects: Who are they?

Authorities allege that Boston bombing suspect Dzhokhar Tsarnaev's friends knowingly decided to remove evidence related to the bombings.

On Wednesday, authorities arrested three friends of suspected Boston Marathon bomber Dzhokhar Tsarnaev. According to the FBI, the three men reportedly went to Tsarnaev's dorm room at the University of Massachusetts-Dartmouth three days after the attack and disposed of evidence that could tie Tsarnaev to the bombings.

Here is a look at who these men are and what they are accused of.

Dias Kadyrbayev, 19

Who he is:

  • Kadyrbayev is a Kazakh national who began studying engineering at UMass-Dartmouth on a student visa in 2011, the same year Tsarnaev enrolled there.
  • He said he became closer to Tsarnaev last year and frequently went to his apartment in Cambridge.
  • Kadyrbayev has been in custody for more than a week on visa violations. Authorities allege that his visa is invalid because he was skipping classes.

What he is accused of, according to the FBI:

  • According to the FBI, Kadyrbayev told his friend Tsarnaev via text message on April 18 that Tsarnaev resembled one of the Boston Marathon bombing suspects, who at the time was unnamed. Tsarnaev texted back "lol" and said to Kadyrbayev: "I'm about to leave if you need something in my room take it."
  • Shortly after, the FBI claims, Kadyrbayev, along with 19-year-old Azamat Tazhayakov and Robel Phillipos, entered Tsarnaev's dorm room at UMass-Dartmouth. Authorities allege that all three men watched a movie in Tsarnaev's room before Kadyrbayev noticed a backpack there, which the three soon discovered contained more than a half-dozen hollowed-out fireworks without their gunpowder.
  • The FBI claims Kadyrbayev knew Tsarnaev was involved with the bombing when he found the fireworks and decided to remove the backpack from the room "to help his friend Tsarnaev avoid trouble."
  • Kadyrbayev’s attorney said his client had nothing to do with the bombing.
  • Kadyrbayev removed Tsarnaev's laptop "because he did not want Tsarnaev’s roommate to think he was stealing or behaving suspiciously by just taking the backpack,’’ the FBI said.
  • After Kadyrbayev, Tazhayakov and Phillipos collectively decided to dump Tsarnaev's backpack, authorities allege that Kadyrbayev placed the bag and firework remnants in a garbage bag that he hurled into a trash bin near his apartment.

What he is charged with:

  • Conspiring to obstruct justice by concealing and destroying evidence.
  • He faces up to five years in prison and a $250,000 fine.

Azamat Tazhayakov, 19

Who he is:

  • Tazhayakov is a Kazakh national and Kadyrbayev's roommate at an off-campus apartment in New Bedford, Mass.
  • Authorities say he and Kadyrbayev hung out with the bombing suspect on and off campus and spoke in Russian.
  • He began attending UMass-Dartmouth in 2011 but was academically dismissed by the university, according to law enforcement officials.
  • He was allowed to return to the United States from Kazakhstan in January despite not having a valid student visa.
  • Like Kadyrbayev, he has been in custody for more than a week on allegations that he was in violation of his student visa.
  • He told authorities that during a meal with Tsarnaev and Kadyrbayev approximately a month before the April 15 attack, Tsarnaev told the men that he knew how to make a bomb.

What he is accused of, according to the FBI:

  • According to the FBI, Tazhayakov, along with Kadyrbayev and Phillipos, returned to his and Kadyrbayev's apartment and collectively decided to dump the backpack "because they did not want Tsarnaev to get into trouble."
  • Tazhayakov's attorney said his client had nothing to do with the bombing.

What he is charged with:

  • Conspiring to obstruct justice by concealing and destroying evidence.
  • He is facing up to five years in prison and a $250,000 fine.

Robel Phillipos, 19

Who he is:

  • Phillipos, from Cambridge, Mass., attended high school with Tsarnaev at the Cambridge Rindge and Latin School. The two graduated in 2011.

  • According to The New York Times, Phillipos enrolled at UMass-Dartmouth after graduation but dropped out soon after. Phillipos lives with his mother, who is from Ethiopia, in Cambridge, WHDH-TV reported.

What he is accused of, according to the FBI:

  • According to the FBI, Phillipos, Kadyrbayev and Tazhayakov decided to remove Tsarnaev's backpack from his room and dump it in the trash.

  • When questioned by authorities, Phillipos originally told them he didn’t remember going to Tsarnaev's room. He later told them the three men drove there but did not enter. Six days later, he recanted and said he, along with Kadyrbayev and Tazhayakov, removed the backpack and laptop from Tsarnaev's room.

  • Phillipos' attorney said his client did not assist in the disposal of the backpack and disputed claims that he made a misrepresentation.

What he is charged with:

  • Lying to investigators about the visit to Tsarnaev's room.

  • If convicted, Phillipos faces a maximum of eight years behind bars and a $250,000 fine.
