It started as a celebration. The Boston Marathon is usually about sweat, charity, and the pride of Boylston Street, but April 15, 2013, changed everything in a flash of white smoke and ball bearings. If you’re looking into what happened to the Boston bombers, the story doesn't actually end with the manhunt that paralyzed a major American city. It’s a messy, ongoing saga of legal appeals, a supermax prison cell in Colorado, and a family tree that completely withered under the weight of radicalization.
The brothers, Tamerlan and Dzhokhar Tsarnaev, weren't masterminds. They were basically two brothers—one an angry dropout and the other a pot-smoking college kid—who decided to tear a hole in the world. People often forget how young they were. Tamerlan was 26. Dzhokhar was only 19.
The Violent End of Tamerlan Tsarnaev
Tamerlan died in the street.
After the FBI released their photos, the brothers panicked. They killed MIT police officer Sean Collier just to get a gun they couldn't even figure out how to use. Then came the carjacking of Dun Meng, a courageous act of survival that actually gave police the GPS coordinates they needed to hunt the brothers down to Watertown.
What happened next was like something out of a bad action movie. A massive shootout broke out on Laurel Street. The brothers threw pressure-cooker bombs at the police. Tamerlan eventually ran out of ammunition and was tackled by officers. He was alive. He was struggling.
Then Dzhokhar, in a desperate, frantic attempt to escape in their stolen SUV, accelerated toward the officers. He missed the cops but drove directly over his own brother. Tamerlan was dragged under the car for about thirty feet. He was pronounced dead at Beth Israel Deaconess Medical Center, his body riddled with gunshot wounds and blunt force trauma from his own brother’s getaway attempt.

Dzhokhar: The Boat, the Trial, and the Death Row Limbo
Dzhokhar didn’t get far. He was found bleeding out in a dry-docked boat named The Slipaway II in a backyard in Watertown. The image of him climbing out, covered in blood, marked the end of the immediate terror, but it was just the beginning of a decade-long legal headache for the U.S. government.
His trial in 2015 wasn't a "whodunit." His own lawyer, Judy Clarke, stood up in front of the jury and basically said, "It was him." The defense strategy wasn't to claim innocence; it was to save his life by arguing that he was under the "total influence" of his older brother. They painted Tamerlan as the radicalized alpha and Dzhokhar as the follower.
The jury didn't buy it. Or at least, they didn't think it excused the carnage. They sentenced him to death.
Where is Dzhokhar Tsarnaev now?
He’s in ADX Florence. That’s the "Alcatraz of the Rockies." It’s a place designed for people the government never wants to see again. We’re talking about a 7-by-12-foot concrete cell. He spends 23 hours a day inside.
If you’re wondering about the status of what happened to the Boston bombers in terms of the legal system, it’s a rollercoaster. In 2020, a federal appeals court actually threw out his death sentence, citing issues with jury selection and the exclusion of evidence regarding a triple murder Tamerlan was allegedly involved in years prior. For a minute, it looked like he might just get life in prison.

But the Supreme Court stepped in. In 2022, in a 6-3 ruling, the high court reinstated the death penalty. Justice Clarence Thomas wrote the opinion, essentially saying the original trial was fair and the jury’s decision should stand. So, Dzhokhar is currently on death row, but don’t expect an execution anytime soon. The Biden administration put a moratorium on federal executions, and the appeals process for capital punishment usually grinds on for decades.
The Waltham Triple Murder: A Darker Backstory
One of the weirdest and most unsettling parts of this whole thing is the 2011 Waltham murders. Long before the marathon, three men—Brendan Mess, Erik Weissman, and Raphael Teken—were found with their throats slit in an apartment. Their bodies were covered in marijuana.
One of the victims, Brendan Mess, was Tamerlan’s "best friend."
For years, this was a cold case. It wasn't until after the bombing that the FBI started looking at Tamerlan. An associate of his, Ibragim Todashev, reportedly started to confess during an interrogation in Florida, implicating both himself and Tamerlan in the murders. Before he could sign the statement, Todashev allegedly attacked an FBI agent and was shot dead. This remains one of the biggest "what ifs" in the case. If the police had caught Tamerlan for the Waltham murders in 2011, the marathon bombing might never have happened.
What about the rest of the Tsarnaev family?
The fallout hit the family hard. The parents, Anzor and Zubeidat, moved back to Dagestan. They’ve spent years giving interviews claiming their sons were framed, despite the overwhelming mountain of video, DNA, and physical evidence. It’s a classic case of cognitive dissonance.

The sisters, Bella and Ailina, stayed in the U.S. but stayed mostly out of the spotlight after some minor legal brushes of their own. The family unit basically vaporized. It’s a stark reminder that radicalization doesn't just kill the victims; it destroys the perpetrator's entire legacy and lineage.
Lessons from the Boston Marathon Investigation
The aftermath changed how we think about "lone wolf" terrorism. It wasn't Al-Qaeda or ISIS sending orders from a cave. It was "Inspire" magazine and YouTube videos. The brothers learned to build bombs from the internet.
The investigation also highlighted the massive breakdown in communication between the Russian FSB and the FBI. Russia had warned the U.S. about Tamerlan’s radicalization years before, but after a brief check, the FBI closed the file. It’s a mistake that haunts the intelligence community to this day.
Actionable Takeaways and Real-World Impact
Understanding the timeline of what happened to the Boston bombers gives us a few concrete insights into modern security and justice:
- Public Safety Evolution: Notice how major marathons and public events now have "no bag" zones and significantly higher surveillance. The Boston "Soft Target" approach was a blueprint for modern urban security.
- The Power of Digital Evidence: This was the first major U.S. terror attack solved largely through "crowdsourcing" and private security footage. It proved that in the modern age, you are always on camera.
- Legal Precedents: The Tsarnaev appeals have clarified how much a judge can limit "mitigating evidence" in death penalty cases. This will affect every federal capital case for the next fifty years.
The Boston Marathon continues. Every year, the city celebrates "One Boston Day" on April 15. It’s a day for service and kindness, a deliberate choice to overwrite the memory of the brothers with something better. Dzhokhar remains in a cell in Colorado, a ghost of a tragedy that the world has largely moved past, even as the legal system continues its slow, methodical march toward a final resolution.
Check the Department of Justice’s official case files or the SCOTUS blog for the most recent filings on the Tsarnaev appeals if you're tracking the minute-by-minute legal shifts. The case is still technically "active" in the lower courts as his team continues to fight the execution order.
