Alex Murdaugh seemed to be in a hurry in the hour after his wife and son were brutally shot to death. The soon-to-be-disgraced Hampton trial attorney sped down a pothole-riddled country road at more than 74 mph on the way to visit his mother that evening, according to new data gleaned from his 2021 Chevrolet Suburban. His speedometer touched 80 mph on the way back home, well over the 55 mph speed limit.
