Overview
When a murder victim was found in the open country with no known perpetrator, the cities nearest to the body were required to conduct an inquest. The elders would measure the distance to determine which city was closest, then that city's elders would perform a prescribed ritual involving a heifer, confession, and prayer to seek God's forgiveness and protection from bloodguilt.
Key Scriptures
"If someone is found slain, lying in a field in the land the Lord your God is giving you to possess, and it is not known who the killer was" (Deuteronomy 21:1, NIV).
"Your elders and judges shall go out and measure the distance to the cities around the one who has been killed" (Deuteronomy 21:2, ESV).
"Then all the elders of that city nearest to the body shall wash their hands over the heifer whose neck was broken in the valley, and they shall testify, 'Our hands did not shed this blood, and our eyes did not see it'" (Deuteronomy 21:6-7, ESV).
