BOSTON (CBS) – The woman charged with hitting and killing two young children in a Revere crash had her bail revoked Monday after prosecutors say she violated the alcohol monitoring condition of her release.

Autum Harris was arrested in December following a crash on Route 145 near North Shore Road in Revere. Police say Harris slammed into a group of people who were standing at a crosswalk in the median.
