I urge you to look into Krystle's story more. She's an absolutely vile person who participated in the torture and attempted murder of her boyfriend, Brandon Green.
The Caselaw link posted by masklinn provides a legal summary of the kidnapping and torture of Green by Skinner and Cole.
However, in contrast, I found the This Land article "Subterranean Psychonaut" by Mason, Sandel, and Chapman to be a fascinating and in-depth read. It's replete with endnotes and provides information about Cole's actions after the police picked up Green.
