Guenther would eventually allow me to use him as an on-the-record source, but his account muddied the waters more than it cleared them. Despite their bombshell evidence of a copycat motive, both he and Whiteley insisted that they simply gave up after the LAPD told them to. Although they knew Beausoleil had an accomplice, and that he’d called someone at the Spahn Ranch, they never even drove out there to question anybody. That didn’t track. Not with these guys.
