On Thursday a South Carolina jury declared Murdaugh, 54, guilty on two counts of gunning down his wife Maggie, 52, and youngest son, Paul, 22 on their family estate on June 7, 2021.
Murdaugh, the scion of an influential legal family in an area west of Charleston, faces 30 years to life in prison for each of the two counts of murder under South Carolina law.
After listening to testimony over five weeks, the jury took only three hours to deliberate before reaching their verdict.
The case has drawn intense media coverage given the family's immense political power in and around Colleton County, where the trial took place.
Throughout the trial, prosecutors portrayed Murdaugh as a serial liar and argued that only he had the means and the opportunity to commit the murders.
