Local coroner's DNA lab processes wide range of cases, analyst says
Summary
Tara, a forensic DNA analyst at the St. Tammany Parish coroner's office, described how the parish-run DNA lab receives evidence from all local law enforcement and develops DNA profiles used in prosecutions. She said property-crime evidence makes up about 40% of the lab's caseload.
Tara, a forensic DNA analyst at the St. Tammany Parish coroner's office, said the parish-run DNA laboratory receives evidence from every local law enforcement agency and develops DNA profiles to support prosecutions. "We service every single law enforcement agency in Saint Tammany Parish," she said, listing agencies such as Covington PD, Slidell PD and the sheriff's office.
Tara said the lab's work is broader than postmortem identifications: while the coroner's office does body identifications when people lack ID, that accounts for a small share of the workload. "Forty percent of our crimes that we process are property crimes," she said, explaining that contact DNA — cells left on tables, doorknobs or firearms — and bodily fluids are commonly tested. The lab issues reports and provides testimony in court when needed.
