Reply To: Yerushalayim Autopsy – what would a Sanhedrin do?

In a din Tora two witnesses and warning would be required. However, the secular authorities may execute murderers even on circumstantial evidence See http://www.theyeshivaworld.com/coffeeroom/topic/capital-punishment/page/3 . As for an autopsy, a Swiss team has invented a non-invasive “virtopsy” conducted with scanning and imaging technology. This should solve the halachic problems.
