Prosecutors concede insanity plea for Morgan Geyser in Slender Man stabbing case

Prosecutors in the Slender Man stabbing have reached a plea agreement that will avoid a trial for the second girl charged in the case.

Morgan Geyser, 15, was scheduled to go before a jury next month, but will instead plead guilty as charged but not be held criminally liable, and instead remain at the state mental hospital where she has been getting treatment for about 18 months.
