(CENTREVILLE) – Several experts took the stand on Thursday during the Andy Brown trial.
Detective-Sergeant Paul Gonyeau serves with the Michigan State Police's Technical Services Department. He testified that he went over the cell phone information from Brown's provider to find out where he was during the morning hours of October 2, 2013, the date that David Locey was shot in his office.
Gonyeau showed where Brown's cell phone pinged off towers and the area where he may have been. He testified that he could not definitively say where exactly Brown was at when the phone calls or texts were sent.
Also testifying for the Prosecution was David Hayhurst a forensic scientist with the Michigan State Police. He performed tests on Andy Brown's clothing and toiletry items looking for blood, but did not find any on those items.
Detective-Sergeant Russell Karsten of the Michigan State Police is a firearms expert who examined the bullets that were retrieved from Locey. He says they were all fired from the same gun and explained there were three possible firearms that the bullets could have been shot through.
Testimony will resume on Tuesday in St. Joseph County Circuit Court.
