The Good Husband Dateline NBC : Season 25 Episode 6

New York, 2011: Tom Kolman, a supervisor, is found dead in his car. Tom's a relatively healthy 40-year-old, so investigators rule out a health condition as the cause of death. But there's no obvious cause of death. Until the toxicology reports come back: Tom had Midazolam in his system, a sedative only available to medical professionals. This opens the door for the investigation.
