Authorities are still hunting for four inmates, including one suspected of killing a man and stealing his pickup truck, who escaped from a Mississippi jail that has been under federal scrutiny. Leake County Sheriff Randy Atkinson told WJTV-TV that the suspect in the killing, 22-year-old Dylan Arrington, is believed to be dead after he barricaded himself inside a burning home near Conway, Mississippi, Wednesday morning. The sheriff also says a deputy was shot but did not provide more information on the deputy’s condition. Multiple law enforcement agencies were searching parts of the state Wednesday. Police say the inmates escaped from the Raymond Detention Center over the weekend.
