GREAT FALLS - Searchers continued Monday looking for Amy Elaine Harding-Permann, who disappeared Sunday.
Harding, a 34-year old nurse at Benefis Health System in Great Falls, was last seen leaving her residence at 343 Flood Road on foot at about 8:30 p.m. on Sunday.
Cascade County Sheriff Jesse Slaughter said during a press conference Monday afternoon that Harding-Permann got into an argument with her boyfriend, John VanGilder, and she then allegedly assaulted him before leaving the house.
VanGilder told police she was not dressed for the weather as she was only wearing a long sleeve shirt and yoga pants.
Slaughter said search crews were called out quickly because Harding was not dressed for the weather. Temperatures at the time were in the 30s, with wind-chills below freezing.
Searchers include personnel from the sheriff's office, Great Falls Police Department, and Malmstrom Air Force Base.
In addition, a helicopter was used along with a drone that has FLIR capabilities. Searchers also used dogs to assist in the search.
Slaughter said they are not asking for volunteers to assist in the search, but will let people know if that changes. He advised that people avoid the area if possible so search crews can perform their duties.
Anyone with information about the woman's whereabouts is asked to call the sheriff's office at 406-454-6979.
