The Bangkok Post said the two unnamed guests already complained of a stenchful smell inside the room they rented at a hotel at the seaside resort in Pattaya, but still agreed to sleep the night anyway.
After they left the next morning, a cleaner noticed blood seeping through the flooring under the mattress. It was then that a dead body was discovered underneath.
The body reportedly belongs to a transgender woman named Amphon Kongsong. She was killed by two teenagers inside the same room following an argument.
According to Col. Apichai Kropphet, chief of the Muang Pattaya police, the victim, who worked at a bar, invited the older boy to check in inside the hotel after meeting through Facebook.
She allegedly offered him a job at the same bar. The 17-year-old then asked his 14-year-old friend to accompany him.
While inside the room, Amphon allegedly tried to convince one of the boys to have intercourse with her. However, the teener refused; leading to a heated argument.
The police also found out the two have previously been arrested for assault-related cases. The suspects have been detained at the Muang Pattaya police station facing charges of premeditated murder and body concealment.
