David,
It was believed to be taken in Johor, one of the state in Malaysia.
Johor is mentioned in a Wikipedia article on reticulated pythons:
"On September 4, 1995, Ee Heng Chuan, a 29-year-old rubber tapper from the southern Malaysian state of Johor, was killed by a large reticulated python. The victim had apparently been caught unaware and was squeezed to death. The snake had coiled around the lifeless body with the victim's head gripped in its jaws when it was stumbled upon by the victim's brother. The python, measuring 23 ft (7.0 m) long and weighing more than 300 lb, was killed soon after by the arriving police, who required four shots to bring it down. [Murphy JC, Henderson RW. 1997. Tales of Giant Snakes: A Historical Natural History of Anacondas and Pythons. Krieger Pub. Co. 221 pp. ISBN 0894649957]"
The same article describeds the geographic range of this snake as:
"Southeast Asia from the Nicobar Islands, Bangladesh, Burma, Thailand, Laos, Cambodia, Vietnam, Malaysia and Singapore, east through Indonesia and the Indo-Australian Archipelago (Sumatra, the Mentawai Islands, the Natuna Islands, Borneo, Sulawesi, Java, Lombok, Sumbawa, Sumba, Flores, Timor, Maluku, Tanimbar Islands) and the Philippines (Basilan, Bohol, Cebu, Leyte, Luzon, Mindanao, Mindoro, Negros, Palawan, Panay, Polillo, Samar, Tawi-Tawi)."
As for appearance, "they are relatively slim for their length and are certainly not the most heavily built."
It could also be a king cobra. Geographic range: "Bangladesh, Myanmar, Cambodia, China, India, Andaman Islands, Indonesia, Laos, Thailand, Vietnam, west Malaysia, Philippines"
The king cobra is an interesting snake in many ways. For example, most snakes hiss when threatened; the king cobra growls! It kills and eats other cobras. Not exactly cannibalism, since the king cobra is a separate subspecies, not a true cobra.
Neither the head nor the skin markings show up very well in the photo, which makes it hard to tell whether this is a king cobra or reticulated python (or something else). The RP, though slim for a python, far outweighs a king cobra. Like 200-300 lbs versus 20-25 lbs.
