Summary of reasons for ruling
Defendant argues the court erred in allowing the witness to testify as an expert. The court disagreed and held that it was not an error. The court held that the witness qualified as an expert. The witness had experience testing firearms, worked in a police lab, made over 100 tests, testified in many cases, and explained his method for examing the gun.

Notes
“There were few decisions with reference to the introduction of expert testimony to identify the weapon from which a shot was fired until recent years, but the science of ballistics is now recognized as one of the best methods in ferreting out crime that could not otherwise be detected. Expert evidence to identify the weapon from which a shot was fired is generally admitted under the rules covering other forms of expert testimony, and it is the modern tendency of the courts to allow the introduction of such testimony, where the witness’ preparation as shown by experience and training qualifies him to give expert opinion on firearms and ballistics tests. In our opinion the witness in this case showed such qualifications.”
