The New Hampshire Supreme Court has rejected the appeal of a woman sentenced to 45 years to life in the beating death of her 3-year-old daughter.
Katlyn Marin was convicted in the 2014 death of Brielle Gage and sentenced on a second-degree murder charge.
Her lawyer argued her conviction should be reversed. On appeal, Marin's lawyer said a judge was wrong to reject an argument that she was in custody before police read her Miranda rights.
An attorney for the state said Marin wasn't told she couldn't call anyone or couldn't leave.
The case prompted calls for reform at the state's Division for Children, Youth and Families, which was involved with the family before Gage's death.
The supreme court on Friday upheld the judge's ruling.
