Murdaugh Killings

Alex Murdaugh listens to testimony during his double murder trial at the Colleton County Courthouse in Walterboro, S.C., Monday, Feb. 27, 2023. The 54-year-old attorney is standing trial on two counts of murder in the shootings of his wife and son at their Colleton County, S.C., home and hunting lodge on June 7, 2021.

A defense expert in the double murder trial of disgraced South Carolina attorney Alex Murdaugh testified Monday he thinks two different shooters killed Murdaugh's wife and son.

While the idea has hovered over the trial because two different weapons were used and no evidence has been presented suggesting either victim tried to defend themselves, crime scene expert Tim Palmbach was the first witness to suggest the two-killer theory in testimony.

Investigators have said 52-year-old Maggie Murdaugh was shot four or five times with a rifle, while 22-year-old Paul Murdaugh was killed by two shotgun blasts near kennels on the family's sprawling Colleton County property on June 7, 2021.
