NBC NATIONAL NEWS — The Sidney, Montana Police Department relied on civilian support over the weekend in the search for a missing teacher.
On Monday they called in trained search teams from surrounding communities to help in the effort.
Sherry Arnold has spent 19 years in the Sidney School District, making an impact on hundreds of children.
"She`s touched a lot of lives, as well as her cohorts in the teaching ranks. Just a phenomenal person. With respect to the students and staff, yes, they`re upset about it. But I think because we pulled together and everybody has contributed where they can, it's been a real help to work through a bad situation," said Daniel Farr, Superintendent of Schools.
That`s why it's not surprising hundreds of volunteers turned out to search for her.
"We`re a small community and we put ourselves in each other's shoes. We just really want to bring Sherry home for the family," said Shelly Haugen, a volunteer from McKenzie County.
Arnold was last seen Saturday when she went for her usual morning jog.
A sneaker is all police have, leading them to investigate the northeast part of Richland County.
They say nothing is off limits, from abandoned homes to culverts.
"We`re interviewing people, trying to find witnesses, trying to find if there`s any surveillance cameras that may have picked something up. We`re just trying all possibilities," said Bob Burnison, Sidney Assistant Chief of Police.
Volunteers are combing through the area, looking for any trace of evidence they can bring back to the Arnold family.
"They`re heartbroken and they`re scared. They`re strong. They`re a really strong family, and they`re leaning on each other and the support of the community, which has been overwhelming," said Haugen.
Sidney Police say many residents are now more cautious and they`re locking their doors.
