Snipped by me -
IMO, I don't think PM was going to do much time at all given his name is Murdaugh. Convicting him would have required a trial in which someone placed him at the wheel of the boat at the time of the crash and a jury of local citizens to convict, all of them knowing how much power the Murdaughs wield.
I imagine that it would have been resolved by plea bargain in which he would have pled guilty under the condition that the procecutor recommended a short sentence to the Court. The friendly judge would then accept it. I am thinking 2 years at most.
As a side note, I grew up in a mid sized, but still small southern town. Decades ago, a mother of three was killed by the black sheep son of a local surgeon when she rand an errand that took her into a stretch of road off of a "cruising" spot known for drag race challenges.
The black sheep was drag racing in his lifted and blinged out truck. In the course of the race, he cut into- or as he claimed, was forced into her lane and hit her head on.
Rumors swirled of blood tests being administered late (the next morning- or the next afternoon?) due to the need to provide "urgent" medical attention to the lightly injured sheep. He passed the test with flying colors. Other rumors had the father being able to remove "personal items" from the truck at the police impound lot that included alcohol and empty beer cans.
What is known is that the Black Sheep's trial was conveniently changed to a county far, far away..... . There, the black sheep eventually pled guilty after delays and negotiations. He was sentenced to about 2 1/2 to 3 years in prison- of which he served about half.
