Happens more often than you think, wood gets stuck, they push it in with their feet or hands
Dunno why your mind went straight to murder lmao
Well I can only think of 2 possible ways. One is murder unlikely but happens
Wood chippers have warnings written all over and thats like #1 rule do not ever put your hands or feet inside. You use another piece of wood to help push branches that sometimes get jammed or you stop the machine and do it safely.
It takes a special kind of individual to use 2 feet inside while the chipper is running. So do not mourn them they fucked around and found out. You cannot cure that.
