BOSTON (WHDH) - Lawyers for Boston Marathon bomber Dzhokhar Tsarnaev filed an appeal of his death sentence on Thursday.

In the 207-page briefing, his lawyers claim Tsarnaev could not receive a fair trial in Eastern Massachusetts because much of the region was affected by the April 15, 2013 attack.

They also say the government used inadmissible evidence during the trial and that Tsarnaev’s constitutional rights were violated when two of the jurors allegedly lied during the selection process.

Tsarnaev was convicted and sentenced to death in 2015 for carrying out the bombings with his older brother, who was killed by authorities.

Three people died and more than 260 were wounded in the attack.
