The FBI is now involved in the investigation nto Sunday's deadly prison riot in Adams County.
They are working to identify which inmates were involved in the uprising and the murder of a young corrections officer. 24 year old Catlin Carithers was killed during the violence.
Authorities say it started with a fight between gangs who turned on the guards.
Several other officers were injured in the riot that lasted almost 12 hours.
One inmate sent us a cell phone picture of a yard inside the compound of garbage bags piling up, along with other images that he says shows they're getting poor treatment in retaliation.
The convict had a cell phone behind bars, even though the devices are banned.
The man’s girlfriend first called us to say her friend wanted to talk about what’s going on in the private, federal prison, which has been on lockdown since the uprising.
A spokesman for Nashville-based Corrections Corporations of America, which owns and operates the Adams County facility, denies inmates are being mistreated. Steve Owen tells us they are getting three meals a day and that employees are behaving in a professional manner and that FBI and Bureau of Prison officials are on site to monitor and observe what’s going on.
