"Ultimately the DA and the grand jury will have to determine whether these individuals should be charged with first degree murder, second degree murder, or negligent homicide."
Mardis was killed when Marksville City Marshals fired on the vehicle he was riding in with his father last week. Ciolino says charges against the men could rise or fall depending on what the grand jury decides.
"That can range in punishments that could be severe as death or less severe as a term of years."
It's reported that City Marshals fired 18 shots into the vehicle. State Police Col. Mike Edmonson says there is body cam footage of the incident and Ciolino says that evidence will be critical in moving this case forward.
"That's the first thing the District Attorney and the grand jury are going to look at in making that charging decision and everything boils down to intent."
