Hundreds of people, including authorities from all over Richland County, spent Saturday searching for a Sidney High School math teacher who went missing Saturday morning.
Sidney Assistant Police Chief Bob Burnison said Sherry Arnold, 43, was last seen at about 6:30 a.m. when she left her home for a morning jog.
When she didn’t return home, a massive search party of more than 200 people was organized and crews spent Saturday scouring the Sidney area.
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.
“We’re still out actively searching,” Burnison said at 4:30 p.m. “She’s an avid runner and we’re searching the areas where she’s been known to run.”
That area includes what is known as the truck route — Ninth Avenues south, east and northeast — in Sidney, and bike and walking paths in town.
Towards the end of the evening, as it got dark, searchers found a shoe that authorities believe Arnold was wearing when she left Saturday morning, Burnison said.
“An item of interest was found in the northeast part of town and we’re definitely following up on that,” he said. “That’s where we’re concentrating our efforts now.”
Burnison said that the Sidney police and fire departments, the Richland County Sheriff’s Office, the Savage Fire Department, the Montana National Guard and more than 100 volunteers, including some using a pair of civilian-owned airplanes, are involved in the search for Arnold.
“We’re still scouring, looking, trying to find people who might’ve seen her,” he said.
Authorities sent home the civilian search crews at sunset on Saturday but planned to continue searching for Arnold throughout the night.
The search will resume again at 8 a.m. Sunday. Burnison said he hopes to bring in a pair of canine search crews and have people searching from horseback as well.
Anyone with information on Arnold is asked to call the Sidney Law Enforcement Center at 406-433-2210.
