The defendant in a St.Louis double-murder trial has been beaten in a holding cell by another inmate. The incident has led a judge to declare a mistrial in the case. Authorities say the inmate who beat Jimmy Davis Love-El apparently knew one of the victims in the case.

Love-El is charged with killing two men in 2009. He suffered some bruises and a couple of black eyes but no serious injuries. The other inmate could be charged.
