The court held that the expert had established the reliability of his testimony through "documentation of the process he used to reach his conclusion," and that there was nothing to to suggest the trial court should have required further information about error rates.

Notes

“The use of expert testimony to identify spent cartridge cases or bullets to a particular firearm has a long history in Louisiana and elsewhere and has been the subject of Daubert challenges in other jurisdictions. . . . The Monteiro case discusses the available literature and evidence regarding the error rate in firearms examination and identification and observes that the extant information about examiner error is limited in its usefulness by the methodology of the studies so far conducted on that topic.”
