Police were first alerted to Ms Louder's disappearance on Wednesday after her roommate realised she had not seen or heard from her for a while.

'She left with just herself ... and it was pouring rain,' Ms Louder's father, Jesse, told KSL.com.

Her mother, Suzie, added: 'Something weird is going on. It's just not normal behavior. We're just trying to do our best to try to find her and hope she is okay.'

Mr Louder said his daughter did not have a history of abnormal behavior, but admitted she had 'a little bit of depression' due to her recent employment status.
