A Devil worshipper who stabbed a 15-year-old boy to death after a Ouija board spelled out the word "kill" was ordered to be detained indefinitely in Broadmoor.
Michael McCallum, 20, turned his bedroom Walworth, south east London, into a shrine to the Devil where he lured Michael Earridge and his friend Stephen Curran, also 15, the Old Bailey heard.
It ended with McCallum sitting astride Earridge and plunging a foot-long combat knife 11 times into his chest and neck, while his horrified friend looked on.
