NORTH CHARLESTON, SC (WCSC) - Michael Slager's lawyers are asking the state to release information regarding an investigation into a SLED agent who worked the Walter Scott shooting case.
In a motion filed on Monday, lawyers say SLED employees intentionally misled them as to Trace Analyst Whitney Berry's unavailability in Slager's 2016 state trial.
Despite being on the witness list, Berry did not testify citing health concerns.
Last week, officials with the Fifth Circuit Solicitor's Office say they learned that there "may be issues" with the quality of forensic gunshot residue analysis cases conducted by Berry at SLED's laboratory.
SLED told the solicitor's office that they reviewed all the 227 cases from Jan. 2, 2015 from Nov. 7, 2016 in which Berry had completed as part of a "corrective action" and identified 34 cases statewide which may be impacted.
According to court records, three of those cases impacted the Fifth Circuit Solicitor's Office.
The other 31 cases were not identified in the motion.
SLED officials say Berry interpreted data collected and wrote two reports regarding the presence or absence of gunshot residue from Slager and Scott.
A mistrial was declared in Slager's trial last year because of a hung jury.
He was charged with murder for the shooting death of Walter Scott.
