TROY - A mother who killed her 21-month-old son last year was sentenced Thursday to 15 years in state prison, according to the Rensselaer County District Attorney's office.

Judge Jennifer Sober imposed that sentence on Kiona B. Jackson, 21, after her Sept. 5 guilty plea to charges of second-degree manslaughter and criminally negligent homicide. She admitted she killed her son Jacquez Jackson.
