Inside info about Jacqueline

I find it so surprising that nobody in her closest circle - family, relatives, dad of Wren or friends of Jacqueline, has given any inside info about this case, not even anonymously here on reddit? I kinda understand the silence from her closest family (grandma) and the dad of Wren because they're probably given some of the money that Wren/Jacqueline makes. But the rest of them - her friends from nursing school or high school or other moms at Wrens kindergarten (is she going to kindergarden?) are being very silent about this! I don't really get the impression that she has any close friends though. What are your thoughts?
