The 10-month-old boy was shaken so severely that his eyes bled and his skull fractured, a prosecutor told Broward County jurors in Fort Lauderdale.

After nine hours of deliberations, those jurors Thursday convicted Allen Rosario, 27, of Lauderhill, of aggravated child abuse and first-degree felony murder in the death of little Anthony Davilas.

Rosario said his girlfriend's son fell off a bed when he went to the kitchen to prepare a bottle.

The child's mother, Sandra Davilas, has supported Rosario.

``I don't believe that he would have ever intentionally or physically hurt my son,'' Davilas, 26, of Fort Lauderdale, said through tears after the verdict. ``All he did was show my son love and care for him just like a father should.''

Rosario was not the child's father. By his own account, he had a hangover when Davilas left for work on the morning of Aug. 30, 2008.

Rosario told detectives the baby stood in his crib, holding the bars, screaming at the top of his lungs, prosecutor David Frankel said in his closing argument Wednesday.

The wailing, hungry baby got the better of Rosario's emotions, Frankel said.

Rosario took Anthony to University Hospital in Tamarac, where he died two days later.

Defense attorney Jim Lewis told jurors Rosario took the blame because he was the last person to spend time alone with the boy. It is not unheard-of for a child to die from a fall, Lewis said.

``There's no evidence that he's an angry, violent, mean person,'' Lewis said of Rosario.

Davilas said previous, unnoticed falls must have compounded her son's injuries for the final fall from the bed to turn fatal, and that wasn't Rosario's fault.

Broward Circuit Judge Ilona Holmes will impose a mandatory life sentence on Dec. 11.
