I do not know if the information was posted earlier, ignore if it has been.
I believe this couple is Lucie Gèlinas and Guy Carignan. The rings she wore were sold all over North and South America because they were very popular. They were so popular according to a Canada news paper source, during the time many of the Indian nations of the southeast wore plastic look alike turquoise and in Canada those rings were sold upwards to $600.00! Apparently in Canada if you wore that type of jewelry you were signaling you were well off. Same is said of the mans ring with the initials. Those initials could have been a family member who passed the ring on, or it could have been stolen, etc. A men’s pinky ring signaled a wealthy individual. Depending on the style, they also could signal other things, like mafia family. Certain mafia families had certain styles. As far as his father being a doctor, I read in one place his father wanted him to go into the “medical field.” But that doesn’t narrow it down. Was his dad a dentist therefore all the thousands of dollars of dental work? Or, if he simply said his dad was a doctor, did he mean medical, veterinarian or simply a PHD of science, math whatever... BUT, one thing that I keep coming back to is the ring and watch. The ring is a Linde Star, and the watch was the official watch of Astronauts or NASA. Those two things always struck me as worth noting together. But one thing that REALLY is interesting is that the day before the killings the IMSA “24 hours of Datona” race was going on & someone had put water in the gas of many of the race cars so that the race had to be postponed while racers flushed their tanks. Not all the racers got the tainted fuel. So Jock Doe has a shirt from one race in 75 and was not to far from where the Daytona race had ended about 24 hours before. The man that was in possession of the gun had a son around the couples age, he and another guy had died of drowning while out in a boat with another friend in 1973. And that area was know to have connections with drug smuggling both on the coast in boats and on the highway. As we know from John Paul Sr & John Paul Jr in that racing circuit, and their connections to drug smuggling and JP Sr’s connection to murders and drugs. Lot and lots of info to digest. And how do we know as some stories suggest, “they stepped from a van before being shot” where did this come from, & how could anyone possibly know that unless they witnessed it? And if they had a car with Washington or Oregon plates... where was it? Who has it? If they had a car why were they hitchhiking?? And I swear I read in even another forum that they were on a motorcycle. ?
