Illinois police captured Morgan Geyser, who was convicted in the 2014 stabbing of a classmate to appease Slender Man, an online character, after she fled a group home in neighbouring Wisconsin where she was being held.
Police said Geyser, 23, removed her bracelet monitoring device and fled the home in Madison on Saturday night and was on the run until her capture on Sunday.
Officers found her at a truck stop in Posen, Illinois, where they said Geyser told them to "just Google" her name and that she had "done something really bad".
Geyser was 12 years old when she stabbed her classmate 19 times. She was sentenced to 40 years in a mental hospital in 2018 and granted conditional release in July.
Geyser was found with a man at the truck stop just outside of Chicago - and about 170 miles south of Madison - after police received reports of a man and woman loitering.
