The father of a friend of Boston Marathon bombing suspect Dzhokhar Tsarnaev spoke in support of his son Sunday, saying he was simply in the "wrong place, (at the) wrong time, with (the) wrong people." 

Amir Ismagulov is the father of Azamat Tazhayakov, one of three friends charged in connection with the case. 

Tazhayakov and Dias Kadyrbayev are accused of obstruction of justice. They have already waived their right to bail. 

Robel Phillipos, charged with lying to investigators, will appear in court Monday and will ask to be released on bond, his lawyers said in a court filing. 

The FBI says that on April 18 the three friends went to Tsarnaev's college dorm room at the University of Massachusetts-Dartmouth. Authorities believe two of the men -- Tazhayakov and Kadyrbayev -- removed items from the room, including a laptop and a backpack loaded with fireworks. 

Here are the latest developments in their cases: 

Azamat Tazhayakov 

Tazhayakov's father, who lives in Kazakhstan, spoke to CNN in New York. He said he met with his son last week for about 40 minutes. 

Both father and son believe in the U.S. justice system, Ismagulov said. The government will get to the bottom of what happened and let Tazhayakov go, said the father, speaking in Russian. 

Tazhayakov is due back in court May 14. He was already in federal custody on immigration charges related to his student visa, having been arrested in the days after the bombings due to his friendship with Tsarnaev. 

The Kazakhstan native is charged with obstruction of justice. If found guilty, he could face up to five years in prison and $250,000 in fines.
