FORT MYERS, Fla.- Two-year-old Brianna Addison died last week, police say, at the hands of her mother's boyfriend. Addison and two other children were left in the care of Derrick Johnson for more than 10 hours.

It's quiet at the Horizons Apartment unit where Brianna was killed. Children's toys are still on the porch. In a new report, police interviewed Brianna's sibling in the hospital who told investigators what happened.

"Johnson gave (Brianna) a 'whooping' in the living room because she was bad...with a belt and a shoe." The girl said her mother was at work when this happened.

Last week, our cameras caught Johnson helping Brianna's mother, Shawna Hall, load another child into a car. He was arrested shortly after.

The report indicates Johnson didn't call 911, instead he called the children's mother for help.
