The search continued Sunday for a missing Sidney High School teacher who did not return home from a Saturday morning run.
Sherry Arnold, 43, was last seen at 6:30 a.m. when she left home to go for a jog. When she didn't return, a massive search party of more than 200 people was organized.
On Saturday evening, searchers found a shoe that authorities believe Arnold was wearing when she left for her run. It was found in the northeast part of town near one of her usual jogging routes.
Citizen search teams were sent home at nightfall, but Sidney Assistant Police Chief Bob Burnison was told nearly 1,000 people turned out on Sunday morning to help look for the missing math teacher.
"We had to limit it to about 300," Burnison said. "We couldn't control that many people."
Arnold is 5 feet, 10 inches tall, weighs 140 pounds and has a slender build with dark hair and brown eyes. She also has scarring on her left leg from cancer treatment.
She was last seen wearing a blue hooded sweatshirt with white stripes, red nylon pants and black leggings.
Citizen search parties are fanning out across the city, searching in alleys and knocking on doors asking if anyone has seen Arnold.
Burnison said a helicopter crew out of Great Falls and people in several airplanes are searching, as well as three K-9 teams on the ground, adding to the already large number of National Guard and law enforcement searchers.
"We are just concentrating a search in town and the surrounding areas," Burnison said.
As of Sunday morning, Burnison said the case is classified as a missing persons case.
