It came to my attention that, for whatever reason, the date of birth on Mikelle Diane Biggs‘s tombstone is wrong. It gives her date of birth as May 31, 1989, making her nine years old when she disappeared. Every other source I’ve seen gives the date as May 31, 1987, which would have made her eleven. I’m sure the 1987 date of birth is right. She was in the sixth grade when she disappeared, and her own sister posted on Reddit about the case and said she was eleven years old.
