A Portales woman accused of killing her own son pleads guilty today.
Twenty-five-year-old Teresa Gilman was also sentenced to 30 years behind bars for child abuse resulting in death and four counts of child abuse.
The ninth judicial district attorney says Gilman's son, six-year-old Lorenzo Cabral, Jr. died from blunt force trauma to the head in January of 2007.
Gilman reportedly believed the child was possessed by the devil.
Three other children were home at the time of the killing.
