Claim 17: “A search for Shannan Gilbert, who disappeared in 2010, prompted the discovery of all of the remains.”

SINGLE SOURCE

No evidence was found for this claim. However, the evidence for Claim 7 notes that the discovery of the remains was prompted by a search for Shannan Gilbert, which suggests a connection, but no source explicitly states the search for Shannan Gilbert *prompted the discovery of all* the remains, making it a single-source assertion based on the context of the evidence.
