Dzhokhar Tsarnaev was sentenced to death today by a 12-member jury in Boston for his role in the horrific attack that killed four and injured hundreds. The 21-year-old will soon be the youngest person on federal death row.

Courtroom analysts report it was Tsarnaev’s lack of remorse that led the jury to reach their decision.

The verdict culminates months of testimony and various phases of the entire process that began in early January. Prior to being transferred to federal prison in Indiana, Tsarnaev will have to listen to impact statements from survivors and victim’s family members.

The families are working directly with criminal lawyers Melbourne in the investigation for the dead of three innocent marathon spectators who were murdered on April 15, 2013:

  • Martin Richard, 8, of Dorchester, Lingzi Lu, 23
  • Boston University graduate statistics student from China
  • Krystle Marie Campbell, 29, a restaurant manager and Medford native

On April 18, Tsarnaev shot 27-year-old MIT Police Officer Sean Collier after failing to steal his gun. The two were planning to drive to New York City to set off more explosives.

“We have always placed our full confidence in the justice system and the decisions of this jury,” said Tom Grilk, executive director of the Boston Athletic Association. “And while another chapter may be over, our thoughts and prayers continue to be with those who lost their lives, the families of the victims, and the survivor community.”
