Yes I did. It was a horrible situation and a photojournalist out of Bangkok, Roger Arnold, went to photograph the aftermath of the killings.
His photos include a closeup of one man who was shot directly in the face. I believe Roger had a fixer, as Laos can be a tough place to photograph once you get out of the tourist zones and into the bushes.
Thanks for keeping abreast of this important under reported story and situation, which is ongoing in many parts of Laos as we speak, including Xieng Khouang (Phonnsavan)
