A guilty verdict was handed down by a judge Wednesday in the bench trial of two grandparents who were charged in their 9-month-old grandson's overdose death. 

Edaliz Torres and Bartolomeo Blackburn were found guilty of endangering the welfare of a child and criminal possession of a controlled substance.

Last summer, the child's mother called 911 and reported her child was unresponsive. She told operators that there was a plastic bag in the baby's mouth. Crews administered CPR and Narcan when the baby was taken to the hospital. 

Investigators later discovered bags of fentanyl in the home.

"I'd be asking for a time served sentence. She did serve time in jail for this. Not a particularly long time, but the remorse and just listening to the 911 tape what happened that day and just the pure panic and horror... She's been through something that I wouldn't wish on anybody, which was believing for a certain period of time that she was going to lose her grandchild," said Torres' attorney, Julie Cianca.

The child's mother, who was home at the time, was never indicted in the case.  

A pre-sentencing hearing is scheduled to take place May 8.
