NEBRASKA CITY, Neb. (AP) — A Nebraska City mother has been convicted of child abuse for having her boyfriend force her two sons to watch the movie “Mommie Dearest.”

Court records say 28-year-old Mary Lucas pleaded no contest to negligent child abuse. Her sentencing is set for April 12.

Authorities say Mary Lucas’ boyfriend at the time duct-taped the unruly 4- and 5-year-old boys to chairs while the movie played as he baby-sat them in August. Authorities say 30-year-old Glenn Oliver says Lucas told him to make them watch the movie, which depicted actress Joan Crawford as a mean mother. Court records say Oliver thought Lucas wanted to show the boys that she was not the meanest mother.

Oliver awaits sentencing Tuesday on two counts of child abuse.
