Photos of food in the room where the murder-suicide occurred showed that some plates had their plastic wrap removed. However, there haven’t been any specific reports of any dishes containing cyanide.

Thai police still need more time to prove whom the cyanide belonged to, because of different evidence and a lot of people involved.

Earlier, autopsy results released on July 17 confirmed that the six people died of cyanide poisoning, a substance that causes acute asphyxia./.VNA
