The justices, by a 6-3 vote Friday, agreed with the Biden administration’s arguments that a federal appeals court was wrong to throw out the sentence of death a jury imposed on Tsarnaev for his role in the bombing that killed three people near the finish line of the marathon in 2013.
The 1st U.S. Circuit Court of Appeals in Boston ruled in 2020 that the trial judge improperly excluded evidence that could have shown Tsarnaev was deeply influenced by his older brother, Tamerlan, and was somehow less responsible for the carnage. The appeals court also faulted the judge for not sufficiently questioning jurors about their exposure to extensive news coverage of the bombing.
...and someone wants to clean up a loose end.
