A horrified doctor said her injuries were the worst the medic had seen in over 20 years.
Now Posey is starting a life sentence behind bars after yesterday being convicted of first degree murder in Pensacola, Florida.
Prosecutor Amy Shea told the two-day trial: “Dericka died face down in a chair in her living room with her knees on the floor, lying face down in the seat of the chair, and the defendant sitting on top of her.
“The defendant admits that she weighs 320 pounds and this is a nine-year-old girl”
Dericka died face down in a chair in her living room with her knees on the floor, lying face down in the seat of the chair, and the defendant sitting on top of her
The girl suffered horrific beatings from her elderly adoptive parents Grace and James Smith and Posey when she misbehaved, the hearing was told.
In October 2017, Posey was woken by a call from Grace, 71, asking her to discipline Dericka for “acting up” with her eight-year-old sister.
"Once her feet hit the floor getting out of bed, she was determined to beat these children," Assistant State Attorney Shea said.
She took a ruler and a thin pipe to give it “weight” and helped Grace Smith whip Dericka.
The girl was then forced to kneel down in front of an armchair and lean her body forward across the seat so her head was face down on the cushion.
Posey then sat on Dericka’s back and she died because she could not breathe.
Dericka was said to have screamed twice that she could not breathe and Posey rang 911 after getting up.
Severe bruising found on Dericka’s bottom in an autopsy was described by the medical examiner as "injury, on top of injury, on top of injury.”
Posey's lawyer Michael Griffith said she had simply been trying to help the Smiths and had not intended to hurt Dericka.
