One half of the duo accused of causing the deaths of two cousins at their home near Vilonia has been sentenced and will spend the rest of his life behind bars for his involvement in the crime.

Ronald Dean Charles, 34, of Cabot pled guilty on Monday to two counts of capitol murder and was sentenced to life in prison without the chance of ever being paroled for his role in the assault and murder of cousins Lonnie Brock, 62, and Bobby Brock, 45, which occurred in August of 2008.

As part of his plea, Charles agreed to provide truthful testimony against Troy Allen Crook, 32, of Jacksonville, who is scheduled to stand trial in August  2012.

Capt. Matt Rice of the Faulkner County Sheriff's Department was the lead investigator on the case and said it was one of the "most brutal" cases that he has ever investigated.
