In Brazil, an alleged gang member was beheaded by members of a rival gang (PCC?) in a wooded area. The killers decapitated him by chopping into his neck with a curved blade agricultural tool that looks like a sickle. My understanding is that the knife is used for cutting sugar cane and banana trees with.
By the looks of it, the victim is already dead when chopping starts. The blood spray accompanying each chop is quite spectacular. I also like the jello chin at the end of the footage.
