Deshandre Billups and Kirk Cartwright, two Florida inmates, planned to sue the Florida Department of Corrections.

They, along with 21-year-old Tony Underwood, smuggled a .25-caliber Beretta into the jail. Once they had the weapon, they shot each other. They said that an unknown assailant shot them as they were praying in their cells.

Cartwright's girlfriend and Billups' mother were arrested Tuesday on charges stemming from the investigation. Arrest warrants have also been issued for Cartwright's sister and Underwood's girlfriend.
