Identity and Capture of the Boston Bomber
The Boston Marathon bombing on April 15, 2013, was carried out by Dzhokhar Tsarnaev and his brother Tamerlan Tsarnaev. The attack killed 3 people and injured more than 260 near the finish line on Boylston Street. Dzhokhar Tsarnaev was captured on April 19, 2013, after a manhunt in Watertown, Massachusetts, following a shooting that killed MIT Police Officer Sean Collier and injured others. The Tsarnaev brothers had ties to extremist ideology and had traveled to the North Caucasus region before the attack. The Federal Bureau of Investigation led the investigation, and the case became one of the most high-profile domestic terrorism cases in U.S. history. For background on the investigation, see the Federal Bureau of Investigation overview of the Boston Marathon bombing.
Law enforcement used surveillance footage, cell phone data, and public tips to identify the suspects. The brothers used pressure cooker bombs and other explosives placed near the finish line. After the initial blast, they killed Sean Collier and later engaged in a shootout with police in Watertown. Tamerlan Tsarnaev died during the confrontation, and Dzhokhar was found hiding in a boat in a backyard in Watertown. He was arrested and later charged with use of a weapon of mass destruction and other federal crimes. The case drew attention to domestic terrorism threats and led to changes in law enforcement coordination and public safety protocols.
Trial, Sentencing, and Legal Outcome
Federal Trial and Conviction
Dzhokhar Tsarnaev was tried in federal court in Boston in 2015. He was found guilty on all 30 counts, including use of a weapon of mass destruction resulting in death and bombing a place of public use. The jury later decided whether he would receive the death penalty or life in prison without parole. The trial included extensive evidence, victim testimony, and expert analysis of the attack and its aftermath. The case was closely watched by legal experts and the public, and it set important precedents for federal terrorism prosecutions.
Death Penalty and Appeals
In 2015, the jury sentenced Dzhokhar Tsarnaev to death, making him the first person sentenced to federal death for terrorism on U.S. soil since Timothy McVeigh. The death sentence was later vacated by a federal appeals court in 2022 due to concerns about juror bias and the handling of evidence related to Tamerlan Tsarnaev's possible involvement in the 2011 triple homicide in Waltham, Massachusetts. The case returned to the sentencing phase, and in 2023, a new jury reinstated the death penalty for Tsarnaev. The U.S. Department of Justice continues to pursue the death sentence, while Tsarnaev remains on federal death row at the United States Penitentiary, Administrative Maximum Facility.
Victims, Financial Impact, and Ongoing Effects
Victim Compensation and Funds
The One Fund Boston was established to help victims and families affected by the bombing, raising more than $61 million in donations. The fund distributed money to victims for medical expenses, lost wages, and other costs related to the attack. The bombing also led to increased security spending by the city of Boston, the Commonwealth of Massachusetts, and federal agencies. The total cost of the attack, including emergency response, medical care, and long-term victim support, has been estimated in the hundreds of millions of dollars.
