- Nicaragua overturned American Jason Puracal's conviction
- Puracal had been sentenced to 22 years in prison
- High-profile Americans had been fighting for his release for two years
- "The whole experience has been very unbelievable," he tells CNN
Every day in his cell in one of the most notorious prisons in Latin America, an American father wrote a letter to his little boy. Jason Puracal would tuck the papers away, trying to fight the fear that his son might grow up never knowing his dad.
"Jabu was my sunshine. My ray of hope. When I was in there -- it was dark ... it was so ... hard ... I just imagined I could see him," Puracal told CNN on Monday night via phone from New York.
Puracal seemed to choke up a little. After all, he was speaking less than two days after gaining the freedom he thought he'd never have again -- the result of a Nicaraguan court system ruling last week that his conviction could not stand.
Puracal took a breath and laughed. He lovingly shushed the loud giggles of his 5-year-old.
"Come on, play!" the boy said as he tugged at his father.
Puracal, from Washington state, had been behind bars since November 2010, when Nicaraguan authorities raided his real estate office in the coastal tourist city of San Juan del Sur and accused him of money laundering, drug trafficking and involvement in organized crime. He was sentenced to 22 years in August 2011.
Puracal survived "day by day, minute by minute," he told CNN's Anderson Cooper in an exclusive interview Monday night.
"It's a fight for your life every second of the day," he said.
For nearly two years, a chorus of supporters -- including a former FBI agent, a U.S. congressman and several noted human rights attorneys -- fought to clear Puracal's name. They said that there was no evidence to support the charges and that the American's prosecution was rife with legal mistakes and misconduct.
Earlier this summer, Puracal's defense team presented their arguments before an appeals court in Nicaragua, which decided last week to vacate all charges against him.
One of Puracal's attorneys picked him up from the notorious La Modelo prison near Managua late last week and drove him out of the gates. Puracal immediately took a hot shower, and then another and another.
The prison is notorious for its harsh treatment of inmates and for housing some of the region's most violent criminals. Puracal said he had been beaten and been refused water and food for days at a time and had developed a painful inflammation in his bowels and lost a lot of weight.
Puracal talked about the experience with Cooper on Monday night.
"It is a notorious prison -- just the conditions and overcrowding of it and the danger of it. What is that first moment like when the gate slams behind you and you realize the reality of where you are?" Cooper asked.
"I was with rapists, murderers and actual drug dealers," Puracal said. "It's a very violent place. There's a lot of tension between different groups in there; not only the conditions, but the other people around you."
There were times, in the beginning, when Puracal just couldn't believe what was happening to him.
"I didn't believe that I was there, and I kept thinking to myself, 'Oh this is just a big mistake' and that they will let me go any day now," he said. "And the whole time, 'Oh yeah, any day now I should be going,' and it just kept dragging on and dragging on."
What is it like being a free man?
"It's wonderful ... it's very overwhelming," Puracal said. "But I'm happy to be back with my family my wife and my son. ... It's still very, very surreal. The whole experience has been very unbelievable."
He said that his sister Janis Puracal, a Seattle lawyer who was his biggest advocate, sometimes was able to visit him in prison. She brought stacks of supportive e-mails. They were from friends and family but also from strangers who heard about his case through the awareness group FreeJasonP.com, which publicized his case.
The e-mails were a huge help, but "there were days where I started losing hope," he said. "It's a very negative environment, that prison."
Puracal meditated on his son. He thought about his Nicaraguan wife Scarlett.
They met not long after he moved from Washington state to the country, first to work as a Peace Corps volunteer and then as a real estate agent.
The couple settled in San Juan del Sur, a popular beach town in southwest Nicaragua.
On November 11, 2010, Nicaraguan police raided Puracal's ReMax office and his home.
Police also took custody of Puracal's truck and the clothes he was wearing; yet 48 hours after he was detained, police asked him to put his clothes back on and get into his truck so authorities could take pictures, according to former FBI Agent Steve Moore, who has reviewed the case documents. He said police then claimed they found a substance that could be cocaine.
"Basic chain of command was not followed," Moore, part of a group of vocal supporters, told CNN in February.
"You can imagine you feel greatly violated that you are being accused of these horrific crimes with absolutely no evidence," Puracal told Cooper. "But I just didn't believe that those things can happen. You don't think that it can happen to you."
By late Monday night, Puracal was exhausted. He kept playing with Jabu, though.
He still has all those papers, the life lessons he wrote for his son.
"I want to turn them into a book for him," he told CNN. "I want him to be able to keep it."
He still loves Nicaragua, he said. He doesn't blame a country for the acts of a few people. He plans to go to graduate school to get a degree in sustainable urban development to do what he began in the Peace Corps years ago.
"I still do love Nicaragua. I still believe in its potential. I still love the people there," he said. "There's wrongful convictions in every country around the world, including the United States, so I can't isolate it just to Nicaragua. And I hope that one day that I'll be able to finish some of the social projects that I was working on."
