A Shreveport officer is testifying in the trial of a man charged with murdering a deputy in Panola County

Nearly five years after the death of Panola County Deputy Chris Dickerson, a Gregory Newson is now on trial for murder. Prosecutors say Dickerson pulled Newson over in the early morning hours of Dec. 31, 2019, for a broken taillight. They say Newson preemptively “executed” Dickerson before they made contact.
