He was tried. He was convicted. Last month, he was sentenced to die for the bombing during the 2013 Boston Marathon that shut down a city and sent the citizens of that city into their homes for days.

Now convicted bomber Dzhokhar Tsarnaev may spend years in a federal prison during his appeal. That appeal could take at the very least 5-10 years while he sits on death row (although Timothy McVeigh was the exception, dying in 2001 after being sentenced in 1997(. The United States Bureau of Prisons, who will take custody of him, has not decided where he will go to wait for either the needle from Uncle Sam or death by the hand of God but Bostonians can rest assured that he will not draw his last breath on this Earth as a free man. That sentencing hearing will take place June 24th.

Tsarnaev will likely end up in one of two high-security detention facilities, Colorado’s ADX or Indiana’s Terre Haute, according to U.S. District Attorney for Massachusetts Carmen Ortiz.

First the judge will hold a hearing where he will formally pronounce the sentence, Ortiz said after a jury decided that Tsarnaev, 21, deserved the death penalty and will then turn him over to the custody of the Federal Bureau of Prisons, which will determine where he should be held. That hearing will take place June 24th in Boston.

ADX, formerly known as the U.S. Penitentiary Administrative Maximum Facility, is likely “the most punitive, rigid, prison in America,” as defense lawyer Judith Clarke put it during Tsarnaev’s trial, arguing for life in prison for her client.

Life at the Florence, Colorado, prison is so difficult that prosecutors had worried jurors would vote for it as the harsher of the two sentences available to them, death or life imprisonment without possibility of release.

Imprisonment at the U.S. Penitentiary at Terre Haute would place Tsarnaev with other federal death row inmates and in the same complex where federal executions are carried out, Robert Dunham, executive director of the Death Penalty Information Center (DPIC) told the Associated Press.

If ADX is known as the highest security prison for prisoners not sentenced to death, Terre Haute’s death row is “the most maximum security of maximum security,” Dunham said.

Once Tsarnaev’s death sentence is confirmed, that would make him one of just 59 prisoners condemned to execution in U.S. federal courts, according to the Death Penalty Information Center and if the sentence is carried out, he would join a group of only three federal prisoners executed since 1988, when the federal governement re-instated capital punishment.

While he was sentenced to die, Tsarnaev’s execution is neither imminent nor guaranteed. It will likely take at least a decade for his lawyers to exhaust all of his appellate options, said Dunham, and anywhere during the process, a court may overturn the death sentence, Dunham said.

“Because there is a death verdict, there will be a thorough appeals process,” he told CNN and Yahoo! News. “If he had gotten a life sentence, this would be over with.”

As far as ADX, it’s located in the foothill of Colorado’s Rocky Mountains. It’s known as the “Alcatraz of the Rockies” and is isolated and Tsarnaev will never get to view the Rockies aside from the occasional glimpse of sky during outdoor exercise periods. It’s home to 416 inmates and he would have for his neighbors some of the most infamous convicts in the United States, including Oklahoma City bomber accomplice Terry Nichols, underwear bomber Umar Farouk Abdulmutallab, and Unabomber Ted Kaczynski.

As far as human contact goes, Tsarnaev would seldom see anyone else as inmates spend an average of about 23 hours a day locked up alone in their cells, according to an audit of the U.S. Justice Department. There, they take meals passed through slots in the metal doors, watch prison television and write letters.

Each cell, under 24-hour surveillance, has a concrete bed, a table, a toilet, and a sliver of a window. A 10 foot by 20 foot (3 by 6 meter) outdoor enclosure slightly extends their world but just for about an hour and a half each day, according to testimony by Mark Bezy, a former federal prison warden.

“They sit in their cells, locked in their cells every day,” Bezy said. Prisoners resort to communicating with each other through the pipes that link their toilets, he added. “No one has ever escaped from ADX,” Bezy said.

ADX, founded in 1994, has been the subject of multiple lawsuits contending that sentences there violate constitutional protections against “cruel and unusual punishment.”

The federal government has housed condemned inmates since 1999 at a high-security institution in Terre Haute, a town of some 60,000 people in western Indiana.

The complex is home to the death chamber where all three prisoners executed by the federal government since 1988 have died by lethal injection, including Oklahoma City bomber Timothy McVeigh. The federal government and the military use lethal injection to kill their prisoners.

As in ADX, federal inmates at Terre Haute’s death row spend about 23 hours each day alone in small cells with a bed, a toilet and a wash station. Tsarnaev would live essentially in solitary confinement while his lawyers attempt to save him from death, Dunham said.

“Death row is supermax,” said Dunham. “It’s extremely, highly restricted.”

So Tsarnaev will sit and watch the clock tick against him. It’s a race to see who gets to kill him first. The federal government will have to wait out the appeals process until all the appeals are exhausted. On the other hand, the man upstairs doesn’t have to wait for appeals.

Dzhokhar Tsarnaev could have lived his American dream. He could have been the first person to find a cure for cancer, AIDS or even autism. Instead, Dzhokhar Tsarnaev pushed an agenda of hate and fear and tried to wage his version of a jihad, a “holy war” of sorts on the United States. Instead, Dzhokhar Tsarnaev was tried and convicted for two murders and hundreds of counts of assault that ruined lives forever and now must take responsibilty for his actions.

For Dzhokhar Tsarnaev, the clock ticks slowly as he will see if the federal government, the same government he despised, gets their revenge or the creator of the world gets his.
