DJG Forensic Consulting in Chula Vista delivers crime scene investigation, bloodstain pattern analysis, and crime scene reconstruction services from Center Street under the direction of a certified forensic specialist holding MPA, CBPA, and CSCSA credentials. The firm provides expert-witness testimony and forensic case review for defense and prosecution attorneys, including criminal-law practitioners at The Sexton Law Firm who handle cases requiring physical-evidence interpretation. DJG's International Association for Identification-approved training curriculum includes a 40-hour Basic Bloodstain Pattern Analysis course covering passive, impact, and transfer pattern classification through lecture, hands-on practicals, and group case presentations. Forensic documentation packages prepared by the firm carry the evidentiary chain-of-custody rigor that notarization specialists at Cal Notary Service apply to sworn affidavits and court-filed declarations. Advanced engagements encompass three-dimensional crime scene scanning, trajectory-rod angle calculations, and full-scene reconstruction reports integrating spatter dynamics, wound-path geometry, and positional analysis for both criminal and civil litigation.
