Lawyers for Boston Marathon bomber Dzhokhar Tsarnaev (joh-HAHR' tsahr-NEYE'-ehv) have started their case by attempting to show that his older brother bought the components used to build two bombs used in the 2013 attack.
A cellphone analyst testified Monday that Tsarnaev's cellphone was used in the southern part of Massachusetts on Jan. 31, 2013, near where Tsarnaev attended the University of Massachusetts-Dartmouth. That's when pressure cookers were purchased at a Macy's store in Saugus, north of Boston. The analyst also said Tsarnaev's cellphone was used in the same location March 6, 2013, when BBs were bought at two Wal-Mart stores in New Hampshire.
Tsarnaev's lawyer admitted during opening statements that he participated in the bombings, but said his older brother, Tamerlan, was the mastermind.
The defense in the death penalty trial of Boston Marathon bomber Dzhokhar Tsarnaev has called its first witness.
The first person to testify for the defense Monday is Michelle Gamble, a field photographer for the FBI. Prosecutors had called her to the stand earlier in the day to testify about a photograph.
The defense asked Gamble where a book titled "Wiring" was found, and she said it was discovered under the couch in the apartment where Tsarnaev had once lived and where his older brother, Tamerlan, Tamerlan's wife and their daughter lived at the time of the bombings.
During opening statements, Dzhokhar Tsarnaev's lawyer admitted he participated in the bombings but said Tamerlan was the mastermind. Tamerlan Tsarnaev died after a shootout with police days after the attacks.
The prosecution in the death penalty trial of Boston Marathon bomber Dzhokhar Tsarnaev has rested its case after displaying haunting autopsy photos of the victims.
Jurors cried as they were shown horrific images of 8-year-old Martin Richard, the youngest person killed in the blast.
After Dr. Henry Nields described Martin's injuries in graphic detail, prosecutor Nadine Pellegrini asked him if he learned during the autopsy how old the boy was when he died.
Nields replied: "He was 8 years old."
Tsarnaev's lawyers did not cross-examine Nields. Prosecutors then rested their case.
It's now time for the defense team to argue their case as they seek to spare their client's life.
Jurors in the trial of Boston Marathon bomber Dzhokhar Tsarnaev are crying as they view an autopsy photo of an 8-year-old boy who was killed in the attacks.
Three jurors openly wept Monday as the chief medical examiner for Massachusetts displayed a photo of a gaping wound in Martin Richard's abdomen.
Dr. Henry Nields says Martin received injuries to virtually every part of his body, including lacerations of his liver, left kidney and spleen. He says Martin's stomach was also ruptured.
Nields says Martin suffered broken bones and third-degree burns. The injuries caused him to bleed to death.
Martin was standing on a metal barricade watching runners cross the finish line of the April 15, 2013, marathon when the bombs exploded.
Jurors in the trial of Boston Marathon bomber Dzhokhar Tsarnaev have been shown the blood-stained, shredded clothing of an 8-year-old boy who was killed in the second blast.
Dr. Henry Nields showed the clothing as he began testifying Monday about Martin Richard's fatal injuries.
Jurors looked at the clothing somberly. One juror put her hand up to her face.
The clothing was shown as Martin's parents listened from the second row of the courtroom. Bill Richard kept his arm around his wife's shoulder.
Martin was the youngest of the three people who died in the bombings. More than 260 others were injured.
Martin's younger sister, Jane, lost a leg in the blast.
The jury in the trial of Boston Marathon bomber Dzhokhar Tsarnaev has been shown a close-up photograph of him standing just feet behind an 8-year-old boy who was killed in the second blast.
The photo was shown Monday as prosecutors called their final witnesses in the first phase of Tsarnaev's federal death penalty trial.
The photo shows several children standing on a metal barricade watching runners cross the finish line. Among the children is Martin Richard, a Boston boy who died in the explosion. Next to him is his 6-year-old sister, Jane, who lost a leg in the blast. Several feet behind them is Tsarnaev.
Through his attorney, Tsarnaev has admitted planting the second bomb. His lawyers say Tsarnaev's older brother was the mastermind of the 2013 terror attack.
A medical examiner testifying in the trial of Boston Marathon bomber Dzhokhar Tsarnaev has described gaping leg wounds that caused a 23-year-old woman to bleed to death from one of the blasts.
Dr. Katherine Lindstrom says Lingzi Lu's femoral artery in her left leg was essentially cut in half, causing her to quickly bleed to death. Lu was a Chinese national and a graduate student at Boston University.
Lu was one of three people killed when twin bombs exploded near the marathon finish line on April 15, 2013. More than 260 others were injured.
During opening statements, Tsarnaev's lawyer admitted that he participated in the bombings but said his older brother, Tamerlan, was the mastermind. Tamerlan Tsarnaev died after a shootout with police days after the bombings.
