After spending more than 810 days in a cramped cell with little more than his books to keep him company, one of Guatemala’s most renowned journalists was released to house detention on Saturday night as he waits to find out whether he will be granted a new trial.

The decision came after a judge ruled Friday that José Rubén Zamora, the founder and publisher of elPeriódico, a leading newspaper in Guatemala that aggressively investigated government corruption, had spent too much time in prison without a trial and that he was not likely to flee.

“I have never wanted to flee Guatemala, which is also my country, not just the country of the authorities in power,” Mr. Zamora, 68, told the judge. “If you place your trust in me, I will honor it.”

Mr. Zamora was convicted last year of money laundering, sentenced to as many as six years in prison and fined about $40,000. He called the charges politically motivated and said they were retaliation for his newspaper’s focus on public corruption.

As part of his detention outside jail, he will be required to report periodically to the authorities and remain confined in his home.

His trial was plagued with irregularities and was broadly seen as fundamentally unfair — another move to undermine democracy and target critical press coverage during the administration of former President Alejandro Giammattei.
