It happened again. A Florida man is being charged with murdering his girlfriend's 18-month-old child. Police say he was babysitting the child while his girlfriend went to work - and he allegedly beat the baby to death.
The baby's mother works for the Florida Department of Law Enforcement.
Adam Rosa was booked a week and half ago on an aggravated child abuse charge.
Police claim that he was watching the 18-month-old daughter of his girlfriend of two months when the child was seriously injured and later died.
Deputies said Rosa first said the baby choked on milk, then he claimed she fell down the stairs.
He later admitted he caused the baby to hit her head on the bathtub, authorities said.
