The public has been given two contradictory pieces of information about Sandra's mental health. I think this could relate to her disappearance.
On March 14, 2020, a family member gave an interview on the episode of the podcast Missing Persons devoted to Sandra's disappearance. The family member was asked if Sandra had a history of mental health or substance abuse issues and the family member answered no, then hesitated and continued to answer no to mental health issues specifically. To my knowledge, this was the first time this question was asked and answered in a MSM interview.
On February 15, 2021, the same family member was interviewed on the podcast The Vanished. On this podcast, the information was volunteered that Sandra had suffered from "bits and pieces of depression throughout her life." The family member said that it was agreed that "it was not a good fit for Sandra to continue to live alone" because of depression issues that Sandra suffered as a result of her father's death. The words used were that Sandra had "struggled" since his death.
IMO...if you are only 54 and your family feels that you are in no mental state to continue to live alone, what does that say about your mental health? I would say it points to a significant mental health issue of one kind or another.
We were also told by family that the Hanson Police treated Sandra's disappearance very seriously and it was on the same level as if Sandra had been a missing child. That's interesting to me, considering that adults are allowed to walk away from the lives if they choose and they don't need to give an explanation to their family. I don't dispute the family's statement but there was no "silver alert" or anything like that declared publicly. However, if what the family says is true, then this could also give credence to police believing there may be a mental health issue.
