PENSACOLA, Florida -- A woman who weighs more than 300 pounds is facing a homicide charge after investigators say she killed a 9-year-old girl by sitting on her as punishment for "being out of control," reports say.

Veronica Green Posey, 64, also is charged with cruelty toward a child, according to records with the Escambia County Jail. She was released from jail Monday after posting a $125,000 bond.

According to the Pensacola News Journal, paramedics were called to a home at 1:35 p.m. Monday. When they arrived, Dericka Lindsay, 9, was found unresponsive.

She was taken to a hospital but died of her injuries.

Posey, who weighs 325 pounds, reportedly sat on the child to punish her. Dericka told Posey and other adults in the room she could not breathe.

When Posey got up, Dericka was unresponsive, the News Journal reports. Posey called 911 and began performing CPR.

Grace Joan Smith, 69, and James Edmund Smith, 62, also were arrested, both charged with child neglect. Smith also was charged with cruelty toward a child, according to jail records. Both remain in jail.

According to the News Journal, Grace Smith told investigators Posey sat on Dericka in an armchair for 10 minutes before the girl complained she couldn't breathe. Smith said Posey sat for another two minutes before getting up, reports say.

The incident remains under investigation by the Escambia County Sheriff's Department and the Florida Department of Children and Families.
