Nathaniel Bar-Jonah (born David P. Brown on February 15, 1957, in Worcester, Massachusetts) is a convicted child abuser.
He was convicted in 1977 of attempted murder of two boys, and then was later convicted in 2000 of sexual assault and torture of another boy.
The latter case attracted sensational headlines, following unproven allegations of cannibalism of a child he had allegedly murdered.
"Bar-Jonah" was sentenced to 130 years in prison, and is currently serving out his term.
