If I'm reading your post correctly, you're suggesting MG had some knowledge of Barry murdering Suzanne.
Yes, I think it is possible that BM slipped up, and said something to her that made her suspicious. I believe this is corroborated with the two men giving her an envelope of money with a warning not to hand over her phone. BM firing her, and calling her a meth head, saying she is mad I fired her. He was clearly giving the impression not to believe a word she says.
Thank you for sourcing this.Actually, the pig story conversation took place on May 9. From the original arrest affidavit, page 50 ("Morgan Gentile interview - May 15th"):
