SCRANTON -- The soiled diapers and empty cigarette packs left behind, the brief sightings by police, may suggest that the sniper suspect is making a cat and mouse game out of the manhunt in the Poconos.
Law enforcement mentioned at a news conference Wednesday that Frein may be doing these things to taunt or tease officers.
State troopers told us it seems Eric Frein has made himself visible at times to police searching for him, knowing they can't catch him and can't positively identify him to shoot.
The little bits of information police have provided have led to all kinds of speculation about who Eric Frein is, what his motivation might be, and what he's doing out in the woods.
Psychologists tell us it's not easy to answer those questions.
A documentary about Vietnam War reenactments is one of the few glimpses we have to help answer the question, just who is Eric Frein?
In an interview from a few years ago, Frein talked about the difficulty finding adversaries in the Pennsylvania woods.
"We had to find them and we just walked around for two days straight. We never did find them."
Police say they found cigarette packs they believe belonged to Frein in the documentary. He even talked about smoking during a manhunt.
"He couldn't smoke because every time he tried to smoke, he said one of my patrols would come close and he'd have to stop and stay real still."
But this documentary certainly doesn't answer why Frein would ambush state police.
Unfortunately, that's not something a psychologist can answer easily either.
"I think it's human nature to want to understand the why in a situation like this. What would motivate someone to do something like this might allow people to have peace of mind," said Renae Courtney of Marywood University Psychological Service Center, adding that there is no way to know.
While police likely know more about Frein, the rest of us have been left with little tidbits.
Psychologist Renae Courtney says that's not enough for a proper evaluation. She's director of Marywood University's Psychological Service Center. She says frein is having a big psychological impact on others.
"I think that it can create incredible stress for a lot of people."
From law enforcement spending many hours searching with a threat out there, to their families worried at home, to the homeowners surrounded by police activity, to those following all of this closely.
"Well, I'm biased, but I unequivocally think people should reach out for help and there's a lot of help in the community."
The Pennsylvania Department of Welfare has set up a helpline for people affected by this manhunt. The number is 800-985-5990 and there are plenty of other place to turn for help if all this is starting to feel a little overwhelming.
