An Alton woman will have to spend at least 17 years in prison after being sentenced to 20 years for the sexual assault of her 5-year-old daughter in July of last year. 23-year-old Danielle M. Armstrong pleaded guilty to predatory criminal sexual assault of a child - a Class X Felony - in May. The Madison County State's Attorney agreed to a cap of 20 years for her and her husband.
Madison County State's Attorney Tom Gibbons says the husband - 33-year-old David B. Armstrong - is scheduled to be sentenced next Tuesday.
The couple, formerly of the 3,700 block of Coranodo Drive, were both charged on July 11,2012. Alton investigators believe it was an isolated incident, saying there is no evidence to suggest there may be more victims.
