72 Hours: True Crime

S03:É304 - S03:E304 - Sweet Killer

An aging hippy is going through bad times. His wife has left him for a lesbian lover, taking their kids. His cancer, once in remission, has returned. When he's found dead in his home with a gut full of antifreeze - "the sweet killer" - it's sad, but not shocking that he looked for an escape in suicide. It's a closed case, until a shocking confession reveals a maelstrom of lies and a story of cold-blooded murder.
