Trace Evidence Analyst Tarah Helsel Testifies in Bermuda

Post by:

Tarah Helsel, RJ Lee Group trace evidence analyst and gunshot residue (GSR) expert, recently testified in a Bermuda murder case. After explaining to the courtroom that lead, barium, and antimony are fused together and released in a cloud when the firearm is discharged, Ms. Helsel went on to clarify that these particles can also be produced by some fireworks and brake pads.

She confirmed that she had found four particles consistent with GSR on gunshot residue swabs containing particulate from the hands of Kiari Tucker, the man accused of shooting and killing Morlan Steede in 2017. She also found particles from his clothing, shoe, and handkerchief, which had been collected by the police at the scene.
