TOPEKA, Kan. (AP) — The Kansas Supreme Court has upheld the involuntary manslaughter conviction of a daycare provider in the 2007 accidental death of an infant.

Michelle Bolze-Sann was sentenced to nearly three years in prison for her role in the suffocation death of the 6-month-old baby. The child died July 2, 2007, after rolling off a bed and becoming trapped between the mattress and the bed’s footboard.

In a ruling released Friday, the state Supreme Court upheld the Shawnee County court verdict. Prosecutors said Bolze-Sann violated state laws requiring napping children under 18 months of age to be in cribs or playpens with narrowly placed slats and protective bumpers.

The Topeka Capital-Journal reports the justices rejected Bolze-Sann’s claim that the state failed to present sufficient evidence establishing that she acted recklessly .
