All I got for backinfo is that the incident happened in Iloilo, the Philippines. By looking at the pics, it would appear that they show the aftermath of suicide. Or murder staged to look like suicide.
The dead guy still holds a pistol in his right hand, but lost his left flip flop and his eye glasses flew off.
No idea what this was all about nor why he would take his life. Props to Best Gore member @delimanu for the pics:
