If you want to know who IK was, listen to Josh Hallmark's podcast, True Crime BS. More insightful, fewer total lies (his daughter's mother isn't "black" Maureen. She's multi-racial native, but go ahead with your binary self.) Even FBI detectives who interviewed him have gone on record to praise Hallmark's handling of the data, and his team is now the ONLY one to have identified actual evidence (a kill kit in La Place, LA) that was not pointed out by Keyes himself. First evidence in 12 YEARS. And now they have corroboration for maps/data pulled from Keyes' computer that will potentially lead to even more evidence, possibly even more unknown victims.
Or pay for a titillating, self-congratulatory thrill read that can't even keep basic facts straight. Prime example of what he meant by "all this true crime bullsh*t"
