“Boston bombings: Suspect's classmates appear in court” http://www.bbc.co.uk/news/world-us-canada-22370695
The three 19-year-olds accused of hindering police investigators appeared in Boston federal court on Wednesday.
Mr Tazhayakov and Mr Kadyrbayev are charged with destroying evidence.
Mr Phillipos, a US citizen, is accused of making false statements to investigators.
They were remanded in custody as a prosecutor argued they all presented a "serious risk of flight".
If convicted, Mr Kadyrbayev and Mr Tazhayakov face a maximum sentence of five years in prison and a $250,000 (£160,000) fine, while Mr Phillipos faces up to eight years in prison and a similar fine.
According to the affidavit*2, Mr Tazhayakov and Mr Kadyrbayev removed items from the suspect's dormitory room at the University of Massachusetts - Dartmouth, three days after the blasts.
When TV news reports aired photos of the bombing suspects, released by the FBI, Mr Kadyrbayev allegedly texted Dzhokhar Tsarnaev to say that he resembled the suspect.
Mr Tsarnaev's response included the phrases "lol" and "you better not text me".
According to the charge sheet, he also texted Mr Kadyrbayev: "I'm about to leave if you need something in my room take it."
Mr Kadyrbayev's lawyer said his client did not immediately think that Mr Tsarnaev was the suspect in the FBI images, and that he did not realise the backpack was evidence.
The affidavit says Mr Kadyrbayev told authorities that he and his two co-accused "collectively decided to throw the backpack and fireworks into the trash because they did not want Tsarnaev to get into trouble".
Mr Kadyrbayev also decided to remove Mr 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.
Investigators say they later found the backpack, along with a homework assignment sheet from a class that Mr Tsarnaev attended, in a landfill.
The court papers do not say what happened to the laptop.
Mr Tazhayakov said that Mr Tsarnaev had explained to the two Kazakhs a month before the attacks that he knew how to make a bomb, according to the affidavit.
