BOSTON Three college friends of Boston Marathon bombing suspect Dzhokhar Tsarnaev were arrested and accused Wednesday of removing a backpack containing fireworks emptied of gunpowder and a laptop from Tsarnaev's dorm room three days after the attack to try to keep him from getting into trouble.
In court papers, the FBI said one of them threw the items in the garbage after they concluded from news reports that Tsarnaev was one of the bombers.
On "CBS This Morning" Thursday, CBS News correspondent Elaine Quijano reported from Boston that investigators recovered the laptop and the backpack last week in a New Bedford, Mass., landfill.
Azamat Tazhayakov and Dias Kadyrbayev were charged with conspiring to obstruct justice by concealing and destroying evidence. A third man, Robel Phillipos, was charged with lying to investigators about the visit to Tsarnaev's room.
In a court appearance Wednesday afternoon, Tazhayakov and Kadyrbayev waived bail and agreed to voluntarily detention. Their next hearing is scheduled for May 14.
Phillipos was ordered held pending a detention and probable cause hearing scheduled for Monday.
CBS Boston station WBZ-TV reports that federal Magistrate Judge Marianne Bowler admonished Phillipos in court, telling him to pay attention and not look down during the proceeding.
Late Wednesday afternoon, the attorneys for the suspects spoke outside of the Federal Courthouse in Boston. They say their clients had no idea the attack was being planned.
"He is just as shocked and horrified by the violence in Boston that took place as the rest of the community is," said lawyer Robert Stahl on behalf of Kadyrbayev. "He did not know that this individual was involved in the bombing. His first inkling came much later. We'll be looking forward to proving our case in court. He did not have anything to do with it."
"Azamat Tazhayakov feels horrible and shocked that someone he knew at the University of Massachusetts-Dartmouth was involved in the Boston Marathon bombing," said Tazhayakov's attorney Harlan Protass. "He has cooperated fully with the authorities and looks forward to the truth coming out. He considers it an honor to be able to study in the U.S., and that he feels terrible for the people who have suffered as a result of the bombing."
Meanwhile, the University of Massachusetts at Dartmouth said that Tazhayakov has been suspended "pending the outcome of the case." The university said Kadyrbayez and Phillipos aren't enrolled and that it's cooperating fully with authorities.
Three people were killed and more than 260 injured on April 15 when two bombs exploded near the finish line. Tamerlan Tsarnaev died after a gunfight with police days later. His younger brother, Dzhokhar Tsarnaev, a 19-year-old sophomore at the University of Massachusetts at Dartmouth, was captured and lies in a prison hospital.
Tazhayakov and Kadyrbayev, who are from Kazakhstan, have been held in jail for more than a week on allegations that they violated their student visas by not regularly going to class at UMass. All three men charged Wednesday began attending UMass with Tsarnaev at the same time in 2011, according to the FBI.
The three were not accused of any involvement in the bombing itself. But in a footnote in the court papers, the FBI said that about a month before the bombing, Tsarnaev told Tazhayakov and Kadyrbayev that he knew how to make a bomb.
Investigators have not said whether the pressure cooker bombs used in the attacks were made with gunpowder extracted from fireworks.
As for what the FBI hopes to learn from the suspects, CBS News correspondent Bob Orr reported that if the agency gets its way, it is likely going to use the charges as leverage to press the suspects for more information about Dzhokhar Tsarnaev and what he was doing before the attack: 'Who was he in contact with?' 'Did he ever talk about actually building bombs?' 'Did he ever travel to a remote site maybe for test explosions?' Investigators also want to know what Dzhokar knew about his brother's radicalization and his possible association with terrorists overseas.
If convicted, Kadyrbayev and Tazhayakov could get up to five years in prison and a $250,000 fine. Phillipos faces a maximum of eight years behind bars and a $250,000 fine.

Authorities allege that on the night of April 18, after the FBI released surveillance-camera photos of the bombing suspects and the three men suspected their friend was one of them, they went to Tsarnaev's dorm room.
Before Tsarnaev's roommate let them in, Kadyrbayev showed Tazhayakov a text message from Tsarnaev that read: "I'm about to leave if you need something in my room take it," according to the FBI.
When Tazhayakov learned of the message, "he believed he would never see Tsarnaev alive again," the FBI said in the affidavit.
It was not clear from the court papers whether authorities believe that was an instruction from Tsarnaev to his friends to destroy evidence.
Once inside Tsarnaev's room, the men noticed a backpack containing fireworks, which had been opened and emptied of powder, the FBI said.
The FBI said that Kadyrbayev knew when he saw the empty fireworks that Tsarnaev was involved in the bombings and decided to remove the backpack from the room "in order to help his friend Tsarnaev avoid trouble."
Kadyrbayev also decided to remove 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 in court papers.
After the three men returned to Kadyrbayev's and Tazhayakov's apartment with the backpack and computer, they watched news reports featuring photographs of Tsarnaev.
The FBI affidavit said Kadyrbayev told authorities the three men then "collectively decided to throw the backpack and fireworks into the trash because they did not want Tsarnaev to get into trouble."
Kadyrbayev said he placed the backpack and fireworks along with trash from the apartment into a large trash bag and threw it into a garbage bin near the men's apartment.
When the backpack was later found in a landfill last week, inside it was a UMass-Dartmouth homework assignment sheet from a class Tsarnaev was taking, the FBI said.
Kadyrbayev and Tazhayakov lived at an off-campus apartment in New Bedford, about 60 miles south of Boston, and got around in a car registered to Kadyrbayev with a souvenir plate that read "Terrorista (hash)1." The car was pictured on Tsarnaev's Twitter feed in March.
The plate was a gag gift from some of Kadyrbayev's friends, meant to invoke his penchant for late-night partying rather than his political sentiments, a lawyer for Kadyrbayev said last week.
Michael McKeown, 20, went to high school with Dzhokjar and Phillipos and served with Phillipos on the Cambridge Kids' Council.
"He wasn't a stupid kid," the Boston University sophomore said of Phillipos. "I'm surprised he would do something this foolish."
Meanwhile, Tamerlan Tsarnaev's relatives will claim his body now that his wife has agreed to release it, an uncle said. The body of Tsarnaev, 26, has been at the medical examiner's office in Massachusetts since he died after a gunfight with authorities more than a week ago.
Amato DeLuca, an attorney for his widow, Katherine Russell, said Tuesday that his client had just learned that the medical examiner was ready to release Tsarnaev's body and that she wants it released to his side of the family.
Tsarnaev's parents are still in Russia, but he has other relatives in the U.S.
