IDK. I remember from the trial the 3 girls that saw RA knew Abby and were actually messaging with her as they left/she arrived. I was wondering whether A&L saw on social media that these girls were out at the park and wanted to join them, but got there too late.Second thing I noted was he mentioned KK and he said it was possible that Abby and Libby were there that day because they were communicating with KK.. but that doesn't mean he had any part in their murder. I know many of us have wondered about that connection. He said they could have been there because of the communications with KK.. but they had nothing to connect him to Delphi or the crime. Unfortunate that it may really be a coincidence that RA was there looking for someone to harm and the girls may have been there thinking a young cute guy they talked to online might be there too.
Just speculating.
