The world waits as Koresh makes new promise of surrender but the FBI's controversial tactics turn the compound into an apocalyptic scene. U.S. Attorney General Janet Reno approved recommendations of FBI officials to proceed with a final advance in which the Branch Davidians would be removed from the Mount Carmel Center by force.
In an attempt to flush Koresh out of the stronghold, the FBI resorted to pumping CS gas into the compound with the aid of an M728 Combat Engineer Vehicle, which was equipped with a battering ram. In the course of the advance, the Mount Carmel Center caught fire under circumstances that remain disputed. Barricaded inside the building, 79 Branch Davidians perished in the ensuing blaze; 21 of these victims were children under the age of 16. Koresh, then 33, died of a gunshot wound to the head during the course of the fire. It is unknown whether he committed suicide or if he was killed.

The images of brothers Tamerlan and Dzhokhar Tsarnaev are released to the public setting off a violent chain of events. Meanwhile, clues from their past tell a complicated story - how was the radicalization of the ethnically Chechen brothers and the existence of potential collaborators. The post-9/11 biases played a role in the investigation.

Following their identification, the Tsarnaev brothers killed an MIT policeman, then kidnapped a man in his car. They had a shootout with the police in nearby Watertown, during which two officers were severely injured (one of whom, Dennis Simmonds, died a year later). Tamerlan was shot several times, and his brother Dzhokhar ran him over while escaping in the stolen car. Tamerlan died soon after.
An unprecedented manhunt for Dzhokhar ensued, with thousands of law enforcement officers searching a 20-block area of Watertown. Residents of Watertown and surrounding communities were asked to stay indoors, and the transportation system and most businesses and public places closed. After a Watertown resident discovered him hiding in a boat in his backyard, Dzhokhar Tsarnaev is cornered into an intense standoff. As officials navigate remaining questions and suspicions, the city emerges Boston Strong.
