I came across this news article dated Feb. 22, 2017. Thought this was interesting....
Abbie Williams. The girls were reported missing around 5.30pm on the day of their hike and found dead a day later Indiana State Police are looking beyond the town of Delphi for a man photographed near the trail around the time a relative dropped the girls off, Sgt. Kim Riley told WLFI-TV in Lafayette.
Authorities said they are expanding the search for a suspect in the killings of two girls
"We are actually expanding out," Riley said. "We want people who may have seen somebody walking, that may have picked up a hitchhiker, that may have seen a hitchhiker around that afternoon."
Snapchat murder girls, 14 and 13, recorded suspected killer ordering them ‘down the hill’
This is one of the things I have referred to in the past
They expanded their search out fairly early and entertained many possible SM connections
I have confidence that they have more narrowly focused their investigation for a specific reason
I just don't know what that reason is
But I think its a very definitive one
