According to Han, she passed her Divemaster certification about a month after the incident and left Roatán. After staying in the United States for about three weeks, she returned to South Korea. At the end of December 2008, Han went to Dahab, Egypt where she taught diving to other Koreans.

On September 22, 2009, Han was extradited back to Roatán via the Netherlands while in Interpol custody. After a short court hearing which Han said she did not understand, she was sent to La Ceiba prison. Han said she was scared of the prison shop "because there are a lot of rapists amongst the males." Han praised her father who visited her at the prison and befriended the guards to make sure that she was treated well. On December 14, 2009, Han was released from the prison on $10,000 bail and has been allowed to remain under house arrest at a church in San Pedro Sula until her trial.

Han's trial was scheduled to be held at Coxen Hole on October 14 to 15 in 2010. The Korean Ministry of Foreign Affairs and Trade sent a diplomat and a forensic expert from the Korean National Institute for Scientific Investigation to assist with the case. Han was defended by attorney Félix Antonio Ávila Ortíz against charges that could have imprisoned her for up to 30 years in Honduras. An additional autopsy report was submitted by Han's defense that indicated that Mast's death may have been caused by a combination of alcohol and drugs. On October 16, Han was found not guilty in a unanimous Verbal ruling by a three-judge panel of the regional court of Roatán. However, the formal hearing to release Han was postponed on November 5 and again on November 19. The official verdict acquitting Han was finally delivered on November 24, 2010. The prosecution has appealed the ruling, though Korean ministry officials believe it unlikely to be overturned. Herbert Mast said that he was not shocked by the verdict. Han plans to return to South Korea.
