EL RENO, Okla. — District Attorney Mike Fields said Thursday a Canadian County jury convicted a man of two counts of first-degree murder for the deaths of Amy and Bryor Gibbons.

The verdict came after a 12-week jury trial that concluded Thursday. The jury recommended sentences of death for both murders.

The jury found Derek Don Posey, 35, guilty of raping and beating to death Amy Gibbons and then setting her house on fire. The fire killed her 5-year-old son, Bryor. The crimes occurred in Calumet in 2013.

The jury deliberated about three hours before announcing its guilty verdict. During the sentencing portion of the trial, prosecutors introduced evidence of other crimes Posey committed over his lifetime: three separate rapes prior to the rape involving Gibbons’ murder; an armed robbery of a convenience store; peeping Tom charges; two jail assaults; and an aggravated assault and battery.

The case was prosecuted by Assistant District Attorneys John Salmon, Austin Murrey and Erika Simpson.

“We’re extremely happy the jury made the right decision and found Posey guilty on all counts. In the sentencing stage, we simply wanted to make sure they had all of the information they needed to make a decision, and then we trusted them to speak for our citizens about what an appropriate sentence in this case is,” Murrey said. “The evidence is clear that Posey presents an ongoing threat to our community.”

“Six years is a long time to wait for justice. It’s been an honor to represent the State in this case, and we’re happy that Amy and Bryor’s family have finally received the justice they deserve,” Salmon said.

Formal sentencing is set for July 22.
