Pattaya detectives have charged Carman with four offences: murder, concealment of a body, moving or destroying a body, and taking a minor aged between 15 and 18 for sexual purposes.  In taped interviews police have released online, Carman addressed Ms Donhomla's family.

He was asked about the visible scratches and bruises on his neck and arms. On camera, Carman said the marks were due to 'the spiders' which he said were 'always' coming out at the condominium where he stayed. Ms Donhomla came from Kalasin Province in northern Thailand near the Laos border and may have been operating with a fake ID.  Thai child protection laws prohibit the sexual exploitation of people under 18. Carman remains in the custody of Pattaya City Police and is undergoing further questioning as investigators continue collecting evidence. A murder conviction in Thailand can result in a life sentence or the death penalty. Sorry we are not currently accepting comments on this article.
