There is a recent "trail murder" case in Zionsville (close to Delphi) that has been posted about here a few times in the off chance it was related. At this time I don't think it is, however, I do think it is interesting to us... LE has made an arrest and it's being reported that the suspect had confessed to his mother (who seemingly did not report him). The article implies that the family knew but did not contact LE themselves.
This is not encouraging news that BG's family may turn him in IMO
