Cary, N.C. — The search will continue Monday morning for a missing Cary jogger.

Nancy Cooper, 34, of Wallsburg Court, went running at 7 a.m. Saturday but did not return home.

"That was a little odd," said neighbor Diana Duncan. "She doesn't stand you up. She'll always call."

Duncan said that Cooper did not take her car, keys or identification when she went out.

A search party on Sunday combed Cooper's running route, which was believed to be the Lochmere Lake and Regency Park areas. Volunteers also plastered flyers with Cooper's photo on buildings and street signs.

"Officers (are) out here on foot ... We've had a K-9 out here," Capt. Michael Williams said. "We have had assistance from the National Guard that have flown routes for us in helicopters."

Divers also searched Lochmere Lake on Sunday as a precautionary measure, officers said.

Cooper was training for a half marathon and is a member of Lochmere Swim and Tennis Club.

"She has two beautiful little girls who I love so much," Duncan said. "We love her so much; we all do. We just have to keep looking on."

Cooper's husband said he and his wife were having marital issues, but he wouldn't discuss them further. He said this had been a very difficult time for his family.

He asked that everyone continue to spread around his wife's photo.

Cooper, originally from Canada, is 5 feet 9 inches tall and weighs about 120 pounds. She has hazel eyes and brown hair that goes just past her shoulders.

She was last seen wearing a T-shirt, running shorts and light blue running shoes.

Anyone with information about Cooper’s whereabouts is asked to call the Cary Police Department at 919-469-4016.
