Sayam was already in prison serving a life sentence for methamphetamines trafficking.
The Supreme Court also reduced the previous court’s 10-year jail term for Sayam’s wife, Sayamol Sirithanakorn, to five years and upheld the previous court’s four-year jail term for Sayamol’s elder sister, Duangta Kanjanaharn. As both women had already been prison that long, they were ordered released.
On October 27, 2004, Sayam, his wife and Duangta were convicted of laundering between Bt200 million and Bt500 million in drug money.
Sayam and his wife were each sentenced to 20 years while Duangta got 12 years.
On October 28, 2010, the Appeal’s Court lowered Sayamol’s sentence to 10 years and Duangta’s to four years because it wasn’t convinced they were involved in some money-laundering activities.
