Thomas Quick as his name was at the time, was a man convicted for child molesting and armed robbery. The police then wanted to question him about other crimes.

He did confess to some crimes, and the investigators then started to press his doctors to give him more and more benzodiazepine (Valium and/or Xanax i think) when he asked for it. Presumably because they wanted to keep him happy, and the confessions to keep coming.

This so becomes a bad circle where he was "rewarded" wit more benzodiazepine for each confessions. Benzodiazepine are highly addictive, and some has claimed this got so bad that even other patients observing this practise wanted to confess crimes so they could get thus drugs to.
