DP is an arrogant sob and marries women half his age. His most recent wife is missing, never been found (several years now), leaving several children in the wake. His wife before that died of "mysterious" causes, a drowning in the bathtub, ruled, at the time, an accidental death. That is the death for which he now stands trial. (The body had been recently dug up and re-examined, resulting in an analysis which said it could not have been accidental.)
Since you are from Louisianna, you probably havent gotten much coverage of this Chicago area case. Anyway, not one single piece of evidence (from what I know) has ever been proferred that would suggest DP complicit.
