grief-stricken, halee agonized over whether she should tell the police over her suspicions. >> she said what if they want to talk to me? i'm like, you talk. you know? >> the more she thought about it, the more she thought about halee. thaddeus had a bad reputation around town. >> halee could be poking a hornet's nest. >> she absolutely could have. >> if she starts making accusations. >> now, halee was dead, and heather wondered if thaddeus killed halee to shut her up. >> i felt like he was looking at serious charges. if i had to look for people who had reasons to hurt her, that would have been number one. >> the day after halee was murdered someone sent heather this snapchat video. it was thaddeus brandishing a gun. you got that video, so that must have really heightened your suspicion. >> oh, the video was huge. i was positive at that point. he did it. >> and heather wasn't the only one pointing the finger at thaddeus.
