This Datebook is darker than usual, but history is not always a happy story. So, a warning: The topic of this Dakota Datebook could be distressing for some listeners. On September 13, 1993, a woman named Sarah was raped in her condominium in Boulder, Colorado. The complex was called Tantra Lake. She managed to call 911 that night and get a full sexual assault examination. Sadly, it would take 11 years to find her assailant and in that time, he would go on to rape four other women at the Tantra Lake complex between 1993 and 1998. He became known as the “Tantra Rapist.”
