In 1999, Dan Schneider - a Louisiana pharmacist - lost his only son to a drug related murder.  Unlike, perhaps, what most of us would do, Dan was relentless in pursuing his son's murderer and kept up an investigation for more than a year to bring the perpetrator to justice.  He finally saw the young man sentenced to 15 years after taking a plea bargain.  Dan's story of investigation and ultimately redemption is the subject of a trending Netflix docu series - The Pharmacist.
