Here's the short version of a sad story:
About 20+ years ago a lady was shot dead while working at a nursery (trees and plants) alongside I-70 east of Columbia, MO. One bulet wound to the head, no witnesses, no likely motive, etc. and the major case squad worked for a couple weeks without any progress. As the local sherriff's deputies went house to house in wider and wider circles in this semi-rural area they broke the case. A man who lived almost a mile away, on the opposite side of I-70 remembered shooting a .22 rifle out of his back door at a rabbit in his vegetable garden. IIRC ballistics confirmed his weapon as having fired the bullet that killed the woman. A ricochet traveled almost a mile and caused a death. That is sobering to all of us who shoot firearms.
