POLSON, Mont. -

The search continues for a Lake County woman who went missing Monday evening. 40-year-old Shannon Turner was last seen Monday morning leaving her Pablo home. She was headed to work, but did not return home that evening.

“On June 30 we got a phone call for a welfare check on Ms. Turner and we've unsuccessfully been able to locate her or her vehicle. It has now turned into a missing person's case and we are asking for help in locating Ms. Turner and, or her vehicle,” said Detective Kim Leibenguth of the Lake County Sheriff's Department.

Detectives also told NBC Montana that Turner used to work at the Lake County Courthouse in the taxes department. She recently quit her job, but came into work on Monday to pick up her last paycheck. She had left her cell phone at home that morning.

“Did she leave for some reason? Until we can find her and talk to her we don't know,” said Leibenguth.

Detectives also looked through surveillance videos in stores Turner commonly shopped in, but have so far been unsuccessful.

"We have followed up on everything that we have gotten so far, as far as local stores here, but so far we have come up empty handed,” Leibenguth said.

NBC Montana sat down with Turner’s husband, Kevin, who who hasn't stopped looking for his wife. He said that he is just at a loss for words and needs answers. He feels that his whole world has been ripped out from underneath him.

In his 20 years of marriage, he has never been apart from his wife for more than three weeks.

Kevin Turner and others have taken the search to Facebook and made a Facebook page called 'Help find Shannon Turner.' They have been updating the page every day since her disappearance and hope to get others to help them in their search.

Authorities see no sign of foul play, but they are worried about Turner’s welfare. This is now a statewide search and anyone with information about Turner’s whereabouts or her vehicle are urged to call the Lake County Sheriff’s Department at (406)-883-7301
