Forensic Files - Season 8 - Eps 26: Letter Perfect
A healthy young man dies mysteriously in his sleep. There are no signs of trauma or injury, but toxicology tests reveal a lethal dose of lidocaine in his blood. Investigators find a suicide note, and presume he killed himself until a forensic linguist examines the note and determines that what the victim said is less important than how he said it.
