I'm not sure if I'm digging on research that has already been discovered. But I decided to look into "As the World Turns", in which Q has mentioned in 10 different drops.
The soap opera "As the World Turns" was live on television when JFK was shot. The live broadcast was interrupted many times as Breaking News covered the assassination. Walter Cronkite (who also did the voice of the owl during the "Cremation of Care" at Bohemian Grove) covered the breaking news. Several times he mentions "Secret Service approached a man and woman on a grassy hill, whom a group of people were huddled around". However, trying to dig on this supposed "man and woman" is extremely difficult and most of what I am reading says that they bolted the scene as soon as the shots rang out.
I bet Q knows who they are…
