I think the fruit-stand statement didn’t have any mention of the name Jack or Jock. I think it’s just the quoted poster thinking of him that way, after all these years of discussion.
Thanks. The fruit stand witness might be like the campground witness, where they are mistaken about the couple.
We know they ate fruit with or without ice cream. A car is mentioned, not a motorcycle.
"The autopsy revealed the pair had eaten fruit or ice cream with fruit not long before they died so investigators were certain the two must have bought the food from a local eatery or store. Someone remembered seeing a couple matching the dead couple's descriptions at a fruit stand that was located off the Florence Highway, but the person couldn't say whether the man and woman were with someone else or if they were riding in a car."
