Ross was arrested and held for five days at a Coxen Hole jail, where he was visited by British consul Mat Harper.[7][14] Ross told the court that he did not want Mast to come to his apartment on the night she died.[13] British officials in Honduras stated that Mast's initial autopsy was "inconclusive" and were uncertain whether Ross would be charged.[8] Han was summoned to the court to make a statement and answer questions as a witness.[1] Ross was conditionally released after surrendering his British passport and was instructed not to leave the island by the Honduran authorities, who were then unaware of his dual citizenship. Ross used his Australian passport to leave the country the next day,[15] while a memorial was being held for Mast. Han said she had not seen Ross since.[16]

Dutch diplomats and private investigators visited Roatán and pressured Honduran investigators to revisit the case.[14] A new forensic report stated that Mast died of blunt force injuries and asphyxiation with evidence of strangulation.[2] Trace amounts of amphetamines were found in her blood.[16] Honduran forensic pathologist Heybee Yessenia Caballero reported that Mast's bruises were consistent with defensive injuries and concluded her death was a "homicide, from the legal medical point of view."[17] An international arrest warrant was issued for Ross through Interpol.[18]

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.[1]

On August 27, 2009, Han was detained at Cairo International Airport on an Interpol warrant as she was leaving Egypt to return to Korea. After questioning by an Interpol inspector, Han said she was sent to a "chicken cage" jail cell in Cairo where she had to sleep on a concrete floor.[9] Han said that her request to contact the Korean consulate in Egypt was denied.[19] Three days after Han's arrest, Ross fled from Singapore to Australia, which does not have an extradition treaty with Honduras, and denied responsibility for the death through his lawyers.[2][20] Australian authorities will not honor an Interpol red notice, which requests extradition.[10]

On September 22, 2009, Han was extradited back to Roatán via the Netherlands while in Interpol custody.[14] 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.[9] 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.[16][21][22]

South Korean president Lee Myung-bak spoke about the case with Honduran president Porfirio Lobo Sosa.

Han publicly appealed to Ross to come forward and exonerate her.[2] Mariska's father Herbert Mast also pleaded with Western Australian authorities to extradite Ross to answer questions about the case.[23] Mariska's sister Amanda said that Ross never contacted the Mast family to explain what had happened.[12] Ross stated that he wanted to get on with his life and asked for privacy.[16] Han's uncle Sung-ho Choi called the charges "total nonsense" and filed petitions with Amnesty International to seek his niece's release.[3][9]

I want to know the truth but I am not the one who has the key... I don't know if he might be able to help clear my name but it would be great if he can and does.

On June 29, 2010, South Korean president Lee Myung-bak met with Honduran president Porfirio Lobo Sosa at the 2010 summit of the Central American Integration System (SICA) and brought up Han's case, stating: "A young Korean woman is on trial in Honduras. I hope you will pay special attention to the issue."[4][24]

Dutch journalist Peter R. de Vries attempted to interview Daniel Ian Ross in Australia about the case.

In August 2010, Dutch crime reporter Peter R. de Vries traveled to Subiaco, Western Australia to interview Ross about the case.[15] Ross called the police when De Vries attempted to contact him at his home on August 19. De Vries was arrested and paid a $200 fine for disobeying a police order to move on. De Vries responded to the arrest by stating: "I didn't touch him, I didn't insult him, I didn't threaten him... This is a homicide case and I tracked him down and now you're putting me in jail. That's the world upside down."[25] On September 6, a Western Australian magistrate rejected an application by Ross for a restraining order against De Vries, who had by then left the country.[26] On November 14, De Vries aired a 31⁄2 hour investigative program about the case on Dutch television.[27] A follow-up report aired on November 22, 2010.[28]

Something may be being organised as a result of the interest by these Dutch journalists.

The dive community and police have presented several theories for Mast's death, including injuries sustained from her accidental fall, decompression sickness mixed with alcohol, battery during an attempted rape, or an accident during rough sex.[14]

Han's trial was scheduled to be held at Coxen Hole on October 14 to 15 in 2010.[1] 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.[29] Han was defended by attorney Félix Antonio Ávila Ortíz against charges that could have imprisoned her for up to 30 years in Honduras.[9][30] 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.[5][6] However, the formal hearing to release Han was postponed on November 5 and again on November 19.[31][32][33] The official verdict acquitting Han was finally delivered on November 24, 2010.[34] The prosecution has appealed the ruling, though Korean ministry officials believe it unlikely to be overturned.[35] Herbert Mast said that he was not shocked by the verdict.[36] Han plans to return to South Korea.[34]

I thought I was going to break down when the verdict was reached, but it didn't really hit me right away... After I spoke with my father from Korea and took other congratulatory calls, I realized I was found not guilty and was really pleased.

After the verdict was announced, Daniel Ian Ross announced through his lawyer from Australia that he was "delighted" that the court case supported his claim that he was not responsible for the death of Mariska Mast. However, Honduran authorities are still seeking Ross for questioning over Mast's death in his apartment.[36] Dutch consul Floris Kluck stated that authorities from Honduras and the Netherlands were working with Australia on a proposal to extradite Ross without a treaty.[38]

There has been co-operation from lots of countries already to see that justice takes place and it would be nice if Australia would do all the best so justice for this Dutch girl takes place.
