Boulder police arrest man for allegedly sexually assaulting a child; additional victims suspected

Boulder police have arrested Bill Karelis (William Lloyd Karelis, date of birth 8/21/47) for Sexual Assault on a Child by one in a Position of Trust.

The victim was allegedly sexually assaulted by Karelis multiple times, beginning in 2000, when she was 13 years old. Karelis was introduced to his victim through his position at the Shambhala, a Buddhist community, as a teacher and leader at meditation retreats.

Boulder police believe that over a span of 30 years there are additional victims. Anyone who believes they or someone they know was victimized by Karelis in the past is asked to call Boulder Police Detective Ross Richart at 303-441-1833 or Detective Heather Frey at 303-441-3369. There is no statute of limitations on sex offenses involving children under the age of fifteen.
