I belong to a facebook group about Sandra's disappearance where Sandra's family member is the moderator. Today the family member shared a link to the following podcast:
Beyond Bizarre True Crime
with the information that episode 6 of the podcast was covering Sandra's disappearance.
The episode is short (only 17 minutes) and there were a few nuggets of new/clarified information:
The rear door to Sandra's house is a sliding door. When Sandra's daughter arrived on Friday morning it was closed but unlocked and she slid it open. Around minute 8:30
At first glance the house appeared completely undisturbed. The bed was partially sagging on one side where the slats had fallen, as if someone had lifted up the mattress and knocked the slats aside. The fitted sheet to the bed was missing. Around minute 9:23
Sandra’s cousin told Sandra's sister (and, later, police) that she and Sandra had spoken when she called Sandra’s house phone on Wednesday while the boys were still there. The two had made a plan for her to pick Sandra up on Wednesday evening and drive her home on Thursday. She never picked Sandra up because Sandra did not get back to her and she was also not able to get hold of her. Police later confirmed that her call to Sandra during the day was the last incoming call that Sandra answered. Around minute 11.
Sandra's daughter and husband hired a PI in the early days of the disappearance. The PI ruled out any involvement by neighbors but brought the family no closer to answers.
Several supposed sightings of her in the Fall River area were false leads.
A few months after the disappearance, when she was examining Sandra's bedroom on hands and knees,
LM spotted a biological substance in that room that forensic examination revealed was blood, and some of it belonged to Sandra. This is described in the podcast description as "a faint spray of blood." After she raised the alarm about this, asking the Plymouth DA to look into the matter, the MA state police took over the case. They searched the home and removed several evidentiary items to the state crime lab for analysis. Results are still pending.
When Sandra’s father died, he left quite a bit of money. The provisions of his will were a matter of contention. It caused a rift in the family. LM is now estranged from her mother’s siblings, who have not been interested in finding Sandra and have not been a help to investigators, in her opinion.
I'll alert on my own post for a moderator to review.
