GPS Data and SCRE 901

· State v. Brown, 424 S.C. 479 (2018) Even though GPS and electronic monitoring are extremely common and used every day, they still must be authenticated under SCRE 901. A witness who is testifying about evidence of GPS location data “should have experience with the electronic monitoring system used and provide testimony describing the monitoring system, the process of generating or obtaining the records, and how this process has produced accurate results for the particular device or data at issue.” The witness does not have to be qualified as an expert.
