The Boston Marathon bombing was carried out by Dzhokhar Tsarnaev and his older brother, Tamerlan Tsarnaev.
Dzhokhar Tsarnaev was convicted of all 30 charges against him, including using a weapon of mass destruction resulting in death. He was sentenced to death in 2015, but his sentence was later overturned by the Supreme Court. He remains incarcerated in a maximum-security prison.
Tamerlan Tsarnaev was killed in a shootout with police following the bombing.
The bombing occurred on April 15, 2013, near the finish line of the Boston Marathon. Two pressure cooker bombs detonated, killing three people and injuring over 260.
The brothers were identified as suspects within days of the bombing and a massive manhunt ensued. Tamerlan Tsarnaev was killed in a shootout with police on April 19, 2013. Dzhokhar Tsarnaev was found hiding in a boat in Watertown, Massachusetts, on April 19, 2013.
The bombing sparked a national debate about terrorism and security. It also highlighted the importance of community vigilance and the need for law enforcement agencies to share information.
