Debora Maruca-Kovac has been sentenced to 90 days in jail for contributing to the delinquency of a minor.
Nineteen-year-old Robert Hawkins had been living in her home prior to his deadly shooting spree at the Westroads Von Maur store last December. He killed eight people before killing himself.
Sarpy County Judge Robert Wester sentenced Maruca-Kovac on Thursday.
The charge is related to a February search of her Bellevue home. Police found 2.5 ounces of marijuana and some drug paraphernalia there. She pleaded no contest to the delinquency charge as part of a deal with prosecutors to avoid misdemeanor drug charges.
