His ears burned to hear the words come out of her own mouth, waiting to prove himself right as he crept up to the tent and tried to make himself look like he belonged there. Looking over as inconspicuously as he could, Charlie realized that the reason he'd become so invisible was because Sarah was making a whole spectacle of herself. No one was giving two flying fucks about him because they were too busy watching the girl fight to get past an officer decked out in kevlar who blocked her path. 
"Please! I just want to talk to someone!" She exclaimed, grabbing the attention of a nearby SBI officer who was minding his business before she'd interrupted him. "I was on the tarmac with Sheriff Peterkin, I know what happened!"
This piqued his interest for sure. Just as the SBI agent was walking over, Charlie felt something clip his shoulder as someone bumped into him while trying to get past. Charlie scowled, then quickly realized that it was Ward Cameron who'd blown past him trying to get to his daughter. 
"Oh my God! I've been looking everywhere for you, sweetheart. We gotta get out of here and let these people do their jobs. I'm very sorry." He grabbed her and started to try and pull her away, but right as Sarah realized he was trying to silence her, she started fighting back. 
"John B didn't shoot Peterkin!" She exclaimed, wrenching herself out of his hold. 
"Sarah!" Ward scolded, then quickly glanced back at the agent who appeared more intrigued now than before to hear more. "I can tell you that is not true, I gave a sworn deposition to the sheriffs department. She wasn't there, she doesn't know."
Sarah's face morphed into one of horror at the falsity of her father's statement. "No, that's a lie! Everything he's saying is a lie!"
"Okay, fine!" Ward snapped, staring his daughter down. He finally released her and gave her the opportunity to speak, his gaze so intimidating, she shrunk beneath him. "Who was it then? Who killed Sheriff Peterkin?"
Sarah looked fearfully up at her father, practically frozen in place. She could hardly move her chest to go through the motions of breathing from how frightened she was. Charlie watched in deep concentration as he waited to see what would happen. Why was Ward testing her this way? Why would he want to keep her quiet, what was he so afraid of her saying?
As Ward and the SBI agent waited expectantly for Sarah to answer, the girl never broke her father's gaze as she whispered, "Rafe. My brother Rafe shot Sheriff Peterkin. I saw. He had the gun."
Charlie refrained from showing too much shock in his expression as he was forced to process what Sarah had said. His initial reaction would've been to call bullshit on the whole thing. Sarah was just saying that to cover John B's ass and she was just as easily influenced to do wrong as Collins was to lie for a Pogue. He would've been the the first to admit that he was wrong, she hadn't been there to turn her boyfriend in and that was respectable. However, she was guilty of being incredibly naive to walk into the police station and make a claim like this when everyone just wants to see the Pogue locked up. 
No one would believe the son of an affluent family with such huge ties to the community was guilty of murder. Charlie wouldn't have believed himself if he hadn't seen the look on Ward Cameron's face as Sarah actually outed him to the cops. His eyes had widened as big as saucers and he'd grit his teeth in an irritable way like Sarah had just imposed a great inconvenience to him. 
Now he was left doing damage control to try and fix his daughter's mistake. "He was home. My wife can attest to that. I apologize." Ward told the SBI agent before moving back to Sarah to coax her into not saying anything more. 
But Sarah just shoved him back with more power than Charlie would've expected a girl of her size to have based on how far Ward had stepped back to regain his footing. Betrayal fueled her movements. "What is wrong with you?" She cried. "How long have you been lying to us?"
