A Fort Campbell woman accused of trying to collect on her Army husband's life insurance policy has been sentenced to 25 years in prison for setting fire to her home and killing two of her children. Billi Jo Smallwood maintained her innocence at her sentencing Thursday in Louisville. 39-year-old Smallwood could have been given life in prison. She was convicted in federal court of maliciously setting fire to the family’s housing unit in 2007 while her children slept inside. Prosecutors say her intent was to kill her husband and cash in his $400,000 insurance policy.
