CALUMET — A Tulsa man was charged Tuesday with first-degree murder in last month's deaths of a Calumet mother and her 5-year-old son.
Derek Don Posey, 30, was charged with two counts of first-degree murder in Canadian County in the deaths of Amy Gibbins, 22, and her son, Bryor, whom firefighters found dead June 16 in a burned home.
Prosecutors allege Posey forcibly raped Gibbins and struck her on the head. They allege that after killing her, Posey set her house on fire. Bryor was in the house and died in the blaze, according to court documents.
Firefighters discovered the bodies about 4:40 a.m. after extinguishing the flames.
Gibbins worked at Premier Chemical & Oilfield Supply west of Calumet, Police Chief Brian Huckabee said.
“She was a good mom and a good person. Everybody knew her,” Huckabee said.
Posey was working in the oil fields around Calumet at the time of the killings, he said.
Posey also was charged with one count of felony debit card theft in the alleged theft of Gibbins' debit card.
Calumet police asked for assistance from the Oklahoma State Bureau of Investigation in the case. Posey was arrested June 25 in Tulsa by OSBI agents, federal agents and Tulsa police, according to an OSBI news release.
He was taken to the Canadian County jail in El Reno, where he is being held without bail.
He is charged in a separate case in Tulsa County with aggravated assault and battery. Prosecutors allege Posey punched a man in the face June 6.
