Since Beirut is going to hang this round, and there are 3 prime suspects, the logical thing for pevergreen to do would be to investigate the other two. That is, The_Stranger and Motep. Give us the results, and we'll hang them both. By the 3rd day, when pevergreen is due to go, we'll have the autopsy for the first of the three. If that result is confirmed, he'll survive for one more day until the second autopsy is done. If either of those results contradicts his investigation, he hangs.

Also, list your results so far so we can have something to look at.
