Point of reference:
I thought when the Dephi story broke, theres an “Unsub” with a connection to luck and the #13. When the case went national and he undoubtedly felt pressure. I thought then said unsub might strike again due to increased pressure. The 13th of the month ticks by, then we have St. Patrick’s day. Then we have this mornings events. I also think its tied to the case in Iowa where two girls went missing, and No links? Well if the Unsub has ties to luck and the #’s 13 and 7 that might be the common ground.
