Madison, Wisconsin authorities say Morgan Geyser, who was granted conditional release earlier this year in the Slender Man case, is missing after she cut off her Department of Corrections monitoring bracelet and left a group home.

Geyser was last seen in the area of Kroncke Drive around 8 p.m. on Nov. 22 with an adult acquaintance, according to the Madison Police Department. Her whereabouts are unknown, and anyone who sees Geyser is asked to call 911.

Madison police said they were notified of her disappearance Sunday morning, Nov. 23, and immediately alerted the public.

An MPD representative, reached by phone, said the department was alerted just before 8 a.m. The department posted on their website about 45 minutes later, and on Facebook at around 10 a.m.

About 12 hours passed between the time Geyser was last seen and the moment the public was notified.
