I have no idea what happened here. It appears to be some kind of murder suicide involving an entire family. Three members of the family were found hanging and two more bodies were found down stairs. Little in the way of info so the floor is open to speculation as the translation offers little insight.
Translation from Thai:
Scary New Year !!! 21:20 prompted the killing lift, kitchen 5 bodies at number 174. Soi Soi 1, Section 2 Intrapituk Was found hanged three dead bodies on the 2nd floor. The ground floor also found another two bodies have covered a total of five bodies. The jurisdiction of police station Bangyeerua
We apologize for this. That is it.
Scary New Year, indeed.
