Summary Answer
The phrase Boston City Bomber refers to Dzhokhar Tsarnaev, who with his older brother Tamerlan Tsarnaev placed a pressure-cooker bomb near the finish line of the 2013 Boston Marathon on April 15, 2013, killing three people and injuring hundreds. Dzhokhar was captured on April 19, 2013, after a massive manhunt in Watertown, Massachusetts, and was later convicted and sentenced to death in July 2015 for multiple federal crimes including use of a weapon of mass destruction. This profile summarizes the verified facts, timeline, and outcomes based on court records and official investigations.
Verified Identity and Role
Dzhokhar Anzorovich Tsarnaev (born July 22, 1993) was a naturalized U.S. citizen born in Kyrgyzstan who became the surviving perpetrator of the 2013 Boston Marathon bombing. Official findings by the U.S. Department of Justice and the U.S. Attorney's Office confirm he and his brother, Tamerlan Tsarnaev, were the perpetrators. Dzhokhar was convicted on 30 counts, including conspiracy to use a weapon of mass destruction, malicious destruction of property resulting in death, and aiding and abetting the use of a weapon of mass destruction resulting in death.
Key Events and Verified Timeline
April 15, 2013: The Bombing
Two pressure-cooker bombs were placed near the finish line of the Boston Marathon. The explosions occurred at approximately 2:49 p.m. EDT, killing three individuals and injuring more than 260 people. The victims were Martin Richard, 8; Krystle Campbell, 29; and Lingzi Lu, 23. Wounding counts vary slightly across reports but exceed 260 acute injuries.
April 18–19, 2013: Manhunt and Capture
In the early morning of April 18, MIT Police Officer Sean Collier was shot and killed in an attempted carjacking. The Tsarnaev brothers were later confirmed as suspects. On April 19, Dzhokhar Tsarnaev was found hiding in a boat in Watertown, Massachusetts, and was taken into custody after a shootout with police that left Tamerlan Tsarnaev dead and several officers wounded.
Legal Outcomes and Sentencing
Dzhokhar Tsarnaev was tried in federal court. In July 2015, a jury convicted him on 30 counts and imposed the death penalty. His sentence was vacated in 2020 by a federal appeals court due to issues with jury selection, and a new penalty phase was ordered. In 2022, a federal judge resentenced him to life in prison without the possibility of parole, a decision that remains legally settled as of the latest publicly available records.

Context and Aftermath
The bombing triggered a large-scale law enforcement response involving the FBI, Boston Police, Massachusetts State Police, and federal agencies. The city of Boston saw widespread impacts, including a citywide manhunt and the lockdown of Watertown. Community resilience followed, marked by public vigils, first responder recognition, and long-term victim support efforts. The case raised questions about domestic extremism, online radicalization, and due process in high-profile terrorism cases.
Common Misconceptions and Clarifications
It is sometimes mistakenly suggested that the bombers acted entirely alone or that other cities or countries were directly involved. Official investigations concluded the brothers were inspired by extremist ideology disseminated online and had some prior communication with suspected foreign entities, but the operational plot was conducted by the two individuals. Additionally, while conspiracy theories occasionally surface, court evidence consistently tied Dzhokhar Tsarnaev directly to the placement of the devices and to post-bombing actions.
Relevance Today
The Boston Marathon bombing remains a significant case in U.S. counterterrorism and criminal law. It influenced federal policies on marathon security, information sharing, and public safety planning for mass gatherings. The legal precedents from the trial and appeals continue to inform how federal courts handle cases involving domestic terrorism and capital punishment. Vigilance, community preparedness, and lessons learned from the response remain relevant for public safety and crisis management planning.
