Did Berniece Baker Miracle (wiki), Marilyn Monroe's half-sister die off radar?
Yes, in 2014 (aged 94–95). Photo there of her grave "Berniece Miracle" with her husband's (Paris Miracle). Other sites online mention her husband by name and its an exact match. Residency sites like Spokeo and Clustrmaps also have no record of her residence beyond the mid-2010s, where she was last recording as living in North Carolina (which neighbours Kentucky) so that too would back up the FindAGrave page, even though the picture itself is strong enough evidence in itself IMO.
Oh dear. Just shows why you shouldn't trust clickbait "news" sites like this, which claim she's still alive without first hand confirmation.
Bad news for @John Key who has her in the Centenarian Deadpool this year, and to anyone who may have picked her on the DDP.
