The mom's torso was found in Manorville in November 2000. Her skull, arms and legs were found at Jones Beach. A few weeks ago, I looked into parental abductions cases and found Yvette Tores/Sabrena Beck (child). What stood out to me was that it mentions Sabrena had her ears pierced. Yvette was last seen in Hauppage (same town Melissa Waterman was last seen alive). I've called in this tip to Suffolk Co Homicide and was told that an investigator would look into it.
If this mom was leaving her husband, she may have resorted to something drastic to financially care for her daughter, including having her daughter with her to meet a john.
