A few months ago, I wanted to try to practice my OSINT skills by looking up missing people by checking out the National Center for Missing & Exploited Children website. One of the people that I was checking on was a 14 year old girl who had been missing for about a week.
I started by looking her up on Facebook and found 2-3 Facebook and Instagram accounts a piece. Nothing of them showed much activity. Then I spread out by looking at the friends that this person took selfies with first. One of the friends had a few pictures with this girl that were fairly recent and within the time that this girl was missing.
