A Janesville Gazette report says 28-year-old Melody N. Butt is accused of violating the terms of her probation. The East Troy woman faces four misdemeanor charges including possession of marijuana.
The state Department of Corrections says it's reviewing the case to decide whether Butt should be sent to prison.
She was convicted of child neglect resulting in death, after she fell asleep while the 11-month-old boy and girl were in the tub. A 10-year prison sentence was stayed, meaning she'd only serve the time if she violated probation.
The voicemail for her previous defense attorney, Joshua Klaff, was full Sunday and wouldn't accept a message.
