Australian filmmaker James Ricketson was convicted of espionage and sentenced to six years in a Cambodian prison, leaving his family "devastated" and worried about his welfare.
The 69-year-old man was sentenced Friday by three judges in Phnom Penh, 15 months after he was arrested after flying a drone without a permit over a political rally.
Nephew Bim Ricketson said the family hoped for the best, but was devastated by the verdict and the long term of the jail.
He was hopeful that his uncle would be declared innocent, inflexible that he was not involved in espionage.
They are extremely concerned about their well-being, noting that they have lost a lot of weight, have skin problems and many undiagnosed health problems.
The legal battle has been a great burden for the family, with their son Jesse Ricketson and his partner Alexandra who are moving to Cambodia.
The defense has a period of 30 days to appeal or accept the verdict and request real pardon.
The family is seeking support from the Australian government to pressure Cambodia to release James Ricketson.
Prime Minister Scott Morrison promised that the Australian government would continue to provide consular support.
