Been lurking here and following this case for a while. I noticed some confusion about Snapchat and just wanted to clarify some things about it, as I use Snapchat frequently.
I haven't read anywhere that Mollie had been using Snap Map, but if a potential perp was friends with her on Snapchat, he/she could theoretically stalk them if she had the service activated. I would hope that LE has investigated ALL of her friends on Snapchat. Usually, to be someone's Snapchat friend means you know them personally to some degree, but recently I have noticed the application has rolled out a new "Quick Add" feature which allows you to add mutual friends or other people whose phone number is not in your contacts (Snapchat accounts are usually linked to a person's phone number). Speaking from experience, I have multiple Snapchat friends who I am not very close with at all, but we added each other through the Quick Add feature. This is Snapchat's way of broadening its social media image. Now, one important note: When someone adds you on Snapchat, you have to add them back for them to communicate with you directly and, usually, to see their stories or their location on the map, if enabled. So, you would most likely know, in some capacity, everyone on your Snapchat list, unless you are careless.
Finally, to add a note about the Snapchat message DJ received from her. Usually, Snapchat will say when a message is "received" too. So, for example, I have a message that I "received" 6 hours ago. It doesn't give the exact time, but a rough approximation of when it was sent to me. After 24 hours though, it would just say "received 2 d ago" for 2 days, for example. My point is: the rough time when Mollie sent her last Snapchat message to her boyfriend should be known, and perhaps 10 PM is indeed when it was actually sent as well.
Makes me so sad (both are public) reading through her posts.
