I've wondered this, too- if they're afraid of the case.
I've also wondered if it's possible he knows someone up the ladder, so to speak.
I do agree with
@tooltimetim in his thoughts about how new daily crimes shove the old ones to the back burner. I know it happens in many cases with LE, especially areas where there's a lot of crime daily and not enough staff on the police force to investigate every single one.
I'd love to see the family call in David Marshburn. We know Tim from Texas Eqqusearch's team has been there twice- so we do know for a fact that Cheryl's family did reach out to Tim and his team. The family has to contact them first, and LE has to agree to allow them to help. That request has to come from the family- so we know behind the scenes, someone from the immediate family did reach out for outside help. The last time Eqqusearch was there, they said that they felt that they were getting close to finding Cheryl- something about having the right pew in the wrong church, or maybe it's reversed- right church, wrong pew. So, in my eyes, that team felt that they are getting close- tells me they may have found something near the area of the suspect's second job.
Cheryl, I hope you are found soon and answers are finally given and the suspect finally arrested for your murder. Many of us here aren't letting this go until you are found. You deserve that and justice!
