LaDay died on April 30 after a struggle with Lumberton Police and deputies. They say LaDay's car ended up in a ditch off Highway 69 near a nursing home, and he ran. Police used a taser on him. He later died at a hospital.
An autopsy ordered by a justice of the peace indicated LaDay died from PCP toxicity and his death was ruled accidental.
The grand jury's decision not to indict the officers brings an end the county's criminal investigation.
"My officers acted appropriately in the circumstances and I know they're gratified with the grand jury's decision," said Lumberton Police Chief Danny Sullins. "I'm relieved. It has to go through the process but we always believed we'd get this behind us and move on. The officers have continued doing their jobs for the citizens of Lumberton and will continue doing so."
