Florida ? A 15-year-old boy threw a football against a pregnant teen’s stomach twice, causing the baby to be born prematurely and die hours later, authorities said.

State prosecutors are reviewing the case to determine whether to file charges. Neither the boy nor the baby’s mother, also 15, was identified.

The boy’s age, intentions and state of mind will be considered, said Maria Schneider, assistant state attorney in charge of the Juvenile Division. She said she likely will make a decision in January; the boy is not in custody.

“This is not straightforward. This is not cut and dry,” Schneider said. “This is a sensitive matter. We didn’t want to rush to judgment.”

Chief Medical Examiner Dr. Joshua Perper said the death was not an accident, noting the boy threw the football twice.

Under Florida law, anyone who causes an unborn baby’s death as a result of an attack on the baby’s mother commits a homicide, Perper said.
