COOPERSTOWN, N.Y. – New evidence has been introduced in the case of an Otsego County mother accused in the deaths of her infant twins.
District Attorney John Muehl says Kimberly Steeley was abusing prescription medications and has three DUI convictions -- information he believes should be used as evidence in her upcoming trial.
Steeley was charged with second-degree manslaughter after her infants, Bonde and Liam, died 11 days apart last May.
The cause of death in both cases was determined to be asphyxiation.
Steeley originally told police she found the babies unresponsive in their bassinets.
Muehl alleges that Steeley smothered the twins in her sleep after she later admitted to sleeping in the same bed with the infants.
Steeley remains free on $100,000 bond after rejecting a plea deal.
If convicted, she could face up to 15 years in prison. Her trial is set to begin Feb. 25, 2020.
