Bizarre Murders (2018)

S1E37 Snake Charmer

In a small Texas town during the late 1970s, a once-prominent rodeo cowboy, now a barber, plots to murder his wife by coaxing a rattlesnake to bite her. When her slow decline frustrates him, he resorts to an even more sinister method, slipping poison into her drink—echoing the deadly fate of his first wife.
