Yes, I realize there are conflicting reports regarding the location of the wine-tasting event. Here’s a couple of links stating it was at JFG’s home:
From
Sud Ouest (translation from the original French)
“It was on the way back from a wine tasting, with friends, on Tuesday, April 29 at around 10 p.m., that Karen Carter was savagely attacked in front of her house. Arriving shortly after on the scene, her new companion, who had organized the evening at his house, found her, lying in her blood, at the foot of her car.”
From
The Times (a British newspaper)
“[JFG], 74, found Carter dying from multiple stab wounds in her driveway at 10pm on April 29, after she had left his farmhouse on the edge of Trémolat where he had hosted a wine-tasting event. He had followed her at a discreet distance to spend the night at her converted barn.”
