On Friday afternoon, Tsarnaev’s friend, Robel Phillipos, was sentenced to 36 months in prison. Former Massachusetts Gov. Michael Dukakis had written a letter of support for Phillipos as a judge prepared to sentence him for lying to the FBI days after the 2013 bombings.

Dukakis, a friend of Phillipos’ family, testified during his trial. In a letter to the judge, Dukakis said he “can’t understand why justice would be served by incarcerating him.”

Prosecutors were seeking a 63-month sentence for Phillipos. However, Woodlock did not understand why the prosecution was seeking that specific sentence.

WBZ-TV’s Ken MacLeod tweeted “Judge struggling with why feds want 63 months for Phillipos — but only 30 (months) for Tamerlan friend (Khairullozhon) Matanov who destroyed computer files.”

Woodlock asked to hear from Phillipos, but his attorney said that he did not recommend his client to speak because of a possible appeal.

The judge says Phillipos has until July 24 to turn himself in to U.S. Marshals.

The sentence given to Phillipos was the most lenient penalty imposed on Tsarnaev’s three college friends who went to his dorm room hours after the FBI publicly released photos of him and his brother as suspects in the attack.

Earlier in the day, Azamat Tazhayakov was sentenced to 42 months in prison. He was convicted of obstruction of justice and conspiracy for removing Tsarnaev’s backpack and laptop computer from his dorm room with another friend.

Prosecutors had recommended a 4-year sentence for Tazhayakov. He was given credit for time served, and will spend another year-and-a-half behind bars.

Tazhayakov tearfully apologized to the people of Boston and to his family for his actions. He also denounced Tsarnaev’s decision to bomb the marathon, saying it made him sick.

But Woodlock said Tazhayakov had committed a “very serious crime.”

“He had an opportunity to do the right thing. He didn’t…For that, he must pay a price,” the judge said.

One juror on the case said Tazhayakov deserved a much stiffer penalty – 10 years in prison.

“I thought he got off very easy. He could’ve prevented MIT, police officer being shot possibly, if he spoke up,” David Archibauld told WBZ-TV. “The FBI would’ve had a good idea who they were looking for.
