Prosecutors seeking the death penalty for a Florida couple accused of abusing and murdering their adopted 10-year-old daughter have released details of the tortures she and her twin brother were subjected to.

Nubia Barahona's decomposing body was found wrapped in plastic in the back of her adoptive father's pest control truck on Feb. 14, 2011, while her twin brother Victor was found in the truck alive, but doused in a chemical, badly burned and suffering from seizures.

Shocking details of what the twins had been subjected to came to light for the first time Monday in an audio statement
