1. Evidence — Evidence of Trailing of Human Beings by Bloodhounds. Evidence of the trailing of human beings by bloodhounds is admissible as a circumstance to corroborate other testimony offered by the state.
2. Same — Proper Training and Tests of Bloodhounds Must Be Shown. The bloodhound in question must be shown to have been trained to follow human beings by their tracks and to have been tested as to its accuracy in trailing upon one or more occasions.
3. Same — Acts of Bloodhounds Admissible Merely as Corroborating Evidence Against Suspect. The evidence of the acts of bloodhounds in following a trail may be received merely as a circumstance or corroborating evidence against a person toward whom other circumstances point as being guilty of the commission of the crime charged.
4. Same — Preliminary Evidence as to Qualifications of Bloodhound. Preliminary to the introduction of this evidence, the court should hear the testimony of witnesses, preferably out of the presence of the jury, as to the blood, training and experience of the dog, and determine as a matter of law whether it is such as to permit its introduction before the jury.
5. Same — Showing That Dog Was Laid on Trail in Question. It should be shown that the dog so trained and tested was laid on the trail, whether visible or not, concerning which testimony has been admitted, at a point where the circumstances tend clearly to show that the guilty party has been or upon a track which such circumstances indicate has been made by him.
6. Appeal and Error — Conclusiveness of Verdict Based Partially Upon Circumstantial Evidence. The verdict of a jury based partially upon circumstantial evidence will not be set aside unless the court finds that the evidence as a whole is insufficient to justify the verdict rendered.
