A boy points a gun at an angry man who ridicules and challenges him to shoot before resorting to threats on the boy's life. This prompts his mother to draw a knife across the angry man's throat, cutting him severely.
A blood trail leads out of the house into a dirt path -- the angry man, still clinging to life despite his bleeding neck wound, is crawling at a feeble pace. The man and woman reach him to finish him off by squeezing the slit in his throat and smothering his mouth. LOTS of gurgling blood seen and heard.
The woman attempts to stab the sheriff, but he evades the attack and starts to choke her. That's when the boy appears and plugs two gunshots into the sheriff, killing him.
