Forensic and anatomic pathologist Harry J Bonnell, MD, operates a consulting pathology practice from San Carlos in San Diego at 6910 Monte Verde Dr in the 92119 ZIP. He earned his MD from Georgetown University School of Medicine in 1979 and built a career that included serving as chief deputy medical examiner for San Diego County, a role that placed him at the center of the regional medicolegal death investigation system. His current practice entity, 4N6 Pathology Inc., provides forensic pathology consultation, autopsy review, and expert case analysis for attorneys, insurance carriers, and families seeking second-opinion evaluation of cause-of-death determinations. Tissue specimen interpretation for surgical and biopsy cases connects his pathology work to the broader medical community, and oral pathology samples from dental surgical practices — including Mission Trails Dentistry in San Carlos — represent one of the specimen pipelines that flow to consulting pathologists in the region. San Carlos sits in the 92119 corridor between Lake Murray Boulevard and Navajo Road, with the Monte Verde Drive address positioned in the residential section near Cowles Mountain's western slope. The forensic pathology subspecialty requires training beyond a standard anatomic pathology residency, covering gunshot wound analysis, toxicology interpretation, decomposition staging, blunt-force trauma pattern recognition, and courtroom testimony preparation for criminal and civil proceedings. Skin biopsy and dermatopathology specimens from cosmetic and medical dermatology practices also intersect with consulting pathology services, and San Diego Cosmetic Laser Clinic in Allied Gardens generates the type of excisional specimens that require independent pathologic interpretation. He is affiliated with multiple San Diego hospital systems for laboratory and pathology consultation.
