Investigators with the Warren County Sheriff’s Office are deciding what steps can be taken next in the days-long search for 63-year-old Harold Lindsey.

Since Friday, search teams have scoured the area where Lindsey’s abandoned truck was discovered on Ring Road and around the area of his Red Oak Drive property.

Warren County Sheriff Martin Pace said the search over the weekend included drones from agencies in Rankin County, which provided the ability to look at nearby ponds that are not easily accessible by foot nor have any place to launch a boat.

The Mississippi Bureau of Investigation issued a Silver Alert for Lindsey on Monday.

Lindsey remained missing as of Tuesday afternoon, and authorities are growing increasingly concerned. Pace said search teams were ready to go quickly if and when investigators are able to learn additional details on where Lindsey might be.

Lindsey is described as a black male, 5 feet, 9 inches tall, weighing 177 pounds with black hair and brown eyes. He was last seen Thursday in the 200 block of Red Oak Drive wearing dark colored jeans and a white T-shirt. Lindsey has a glass right eye.

Pace said Lindsey is a diabetic and may or may not have had his medication. Family members said when he is not on his medication he becomes disoriented and confused.

Pace said deputies responded to a call around 10 a.m. Friday of an abandoned pickup truck on Ring Road. They found Lindsey’s red Ford Ranger pickup apparently stalled out on Ring Road with its hood up.

While a deputy stayed with the truck, another deputy went to Lindsey’s home but he was not there. The deputy talked with neighbors and family members, but no one knew where he was.

The neighbors said he had not returned home and had not been seen since Thursday.

Pace said deputies searched a heavily wooded area adjacent to where the truck was found. Saturday, the search was joined by the Central Mississippi Overland Search and Rescue Team, a volunteer organization composed of sheriff’s deputies and volunteer firefighters from Central Mississippi who participate in search and rescue operations. The sheriff’s office, he said, is a member of the organization.

Anyone with information on Lindsey’s whereabouts is urged to call the Warren County Sheriff’s Office at 601-636-1761 or 911.
