A suspect being held in custody on suspicion of fatally stabbing two of his family members is now being held at the Osage County Jail.
Police told KTUL that Devin Stanley was taken into custody Tuesday afternoon in north Tulsa. He is being held on first degree murder complaints.
Information from the Osage County Sheriff's Office states that Stanley was transferred to Pawhuska for further questioning. Formal charges are expected this week.
Stanley's arrest comes after 71-year-old Esther Driskell was found stabbed to death at her home Monday evening. Later on Tuesday, her 16-year-old granddaughter, Larisa Fraley, was found dead at a different location near Skiatook Lake.
Officials told KTUL that Stanley is the grandson of the woman killed last night and the brother of the girl found today.
Officials said that an oilfield worker discovered the 16-year-old in Driskell's van. He notified authorities Tuesday morning.
Both victims were reportedly stabbed to death at each scene. Those wanting to help the family cover funeal expenses can make donations to a memorial fund at RCB bank, Esther Driskell & Larisa Fraley, account number - 110708974
