A trial has been postponed for a former Episcopal bishop who is charged in the drunken-driving death of a bicyclist in Maryland.

Heather Cook's trial was scheduled to start Thursday in Baltimore, but instead Judge Wanda Heard granted Cook's attorney's request for a postponement after Cook waived her right to a speedy trial. The trial is now set for Sept. 9.

Cook pleaded not guilty during her arraignment in April. She resigned from her post with the Episcopal Church, and church officials revoked her clergy credentials.

Cook faces charges of vehicular manslaughter, drunken driving and distracted driving stemming from a Dec. 27 crash. Prosecutors say Cook was drunk and texting when she fatally struck 41-year-old Tom Palermo on his bicycle.

Cook had been the second-highest ranking Episcopal leader in Maryland.
