Well, technically speaking, no crimes were comitted at Apalachin. The delegates started to run out of there because they ddn´t want to face scrutiny if caught (and seen)...with eachother. Many of them were known criminals while some of them were basically unknown to LE.

A big chunk of them were later subpoenaed to grand juries. But when they refused to speak, they were charged with contempt of court. Most of them were sentenced to prison, but the sentences were all reversed with the help of skilled lawyers during successful appeals.
