More than 40 months after death sentencing, lawyers for Boston bomber Dzhokhar Tsarnaev file their 1000+-page appellate brief with First Circuit

As reported in this local article, headlined "Lawyers: Tsarnaev ‘should not have been tried in Boston’," a very long appellate brief has been filed in a very high-profile federal capital case.  A federal jury handed down Dzhokhar Tsarnaev death sentence way back in May 2015, a full month before Donald Trump had even announced he was running for President.  But now, as Prez Trump heads into the second half of his term, Tsarnaev's team of lawyers has fully briefed his complaints about his trial and sentencing.  Here are the basic details:

Boston Marathon bomber Dzhokhar Tsarnaev’s appellate team presented their oft-delayed opening argument Thursday, urging sparing him a federal execution and allowing him to be retried for the 2013 Patriots Day terror attack that killed an 8-year-old boy and two women.  Their premise is summed up in the opening line: “This case should not have been tried in Boston.

“Forcing this case to trial in a venue still suffering from the bombings was the District Court’s first fundamental error, and it deprived Tsarnaev of an impartial jury and a reliable verdict, in violation of the Fifth, Sixth, and Eighth Amendments,” the brief states.

The partially redacted document filed in the U.S. Court of Appeals for the First Circuit spans 1,124 pages, nearly half of which is the 500-page opening brief alone.

Absent a new trial, Tsarnaev’s team is asking the Appeals Court to reverse his death sentence and order a punishment of life imprisonment.

Tsarnaev, 25, has been in solitary confinement at the federal Supermax prison in Florence, Colo., since his 2015 conviction.  Tsarnaev’s trial attorneys made repeated bids for a change of venue.  His appeal focuses on and echoes several familiar protests raised during his trial, chief among them the argument that he was a pawn of his domineering big brother, Tamerlan Tsarnaev.

Among other things, the public defenders accuse Tsarnaev’s jury forewoman, a restaurant manager his attorneys tried to get removed, of retweeting a social media post calling the University of Massachusetts Dartmouth sophomore a “piece of garbage”  before she received a juror summons, but that she claimed during questioning for her suitability to serve she had not “commented on this case.”  A second juror, a male municipal worker, outright “disobeyed the Court’s instructions,” the brief asserts, by joining a Facebook discussion about the case before he was seated....

Tsarnaev’s appeal blames his 26-year-old brother for his involvement, calling Tamerlan “a killer, an angry and violent man” who “conceived and led this conspiracy.” And but for his influence, “Jahar would never have been on Boylston Street on Marathon Monday.

“Tsarnaev admitted heinous crimes,” the lawyers acknowledge, “but even so — perhaps especially so — this trial demanded scrupulous adherence to the requirements of the Constitution and federal law. Again and again this trial fell short.”

The Tsarnaevs detonated two homemade pressure-cooker bombs packed with shrapnel near the marathon finish line in Copley Square 12 seconds apart on April 15, 2013.  Three spectators were killed — 8-year-old Martin Richard of Dorchester, Krystle Campbell, 29, a restaurant manager from Medford, and Boston University graduate student Lingzi Lu, 23.  More than 260 other people were injured. Sixteen of them lost limbs in the blasts.  Three days later, the brothers shot and killed MIT Police Officer Sean Collier, 27, in his cruiser during an ambush on campus and failed attempt to steal his service weapon.

UPDATE: Thanks to a helpful tweet, I now see that the 500-page brief is available at this link. And there I noticed the final notable section starts this way:

XV. Under The Supreme Court’s Eighth Amendment Jurisprudence, This Court Should Vacate Tsarnaev’s Death Sentences Because He Was Only 19 Years Old At The Time Of The Crimes.

Tsarnaev was just 19 years old when he committed the crimes for which he was sentenced to death. According to now well-established brain science, and increasingly reflected by changing law around the country, the physical development of the brain and related behavioral maturation continues well through the late teens and early 20s. Consistent with the Supreme Court’s Eighth Amendment jurisprudence and a recent resolution adopted by the American Bar Association, this Court should hold that those who commit their crimes as “emerging adults,” when they were under 21 years old, are categorically exempt from the death penalty.
