The husband of a teacher who vanished in Maine over the weekend said she had been stressed and worried before her disappearance.
Kristin Westra, 47, was last seen at her home in North Yarmouth Sunday evening, the Cumberland County Sheriff's Office said.
Her husband, Jay Westra, told NBC News his wife had gone to see a "licensed clinical nurse practitioner" on Sunday. She was reported missing Monday after she had recently had trouble sleeping.
He also said his wife had a safety assessment and she was deemed not to be at risk to harm herself or anyone else.
"She expressed that she had had some sleepless nights and was worried," Westra told the news outlet.
Her family is shocked by her disappearance.
She is the "last person that would do something like this," Westra's brother, Eric Rohrbach, told ABC News. "This is very abnormal."
Jay believes his wife left their bed before dawn Monday morning. He said he found their back door slightly open when he awoke around 3:30 a.m. to find Westra gone.
On Monday, he reported her missing to authorities after searching the town on his own to find her.
"We're searching everywhere that we may think she may be, may have gone, may have liked," Capt. Scott Stewart of the Cumberland County Sheriff’s Office said. "We're still investigating this as a missing person, looking for a positive resolution."
Westra is 5 foot, 10 inches tall and weighs 140 pounds. She has brown hair and brown eyes, according to the sheriff's office.
