FOX23 learned new information Friday about a developing story we’ve been following involving a high-profile double homicide in Skiatook.
Michael Stanley, 19, was arrested Tuesday in connection with both killings, but Friday FOX23 learned how an unsuspecting couple played a role in helping Stanley leave town.
New documents were filed after first-degree murder charges were officially filed against Stanley.
Skiatook police said Stanley stabbed his grandmother, Esther Driskell, Monday and then took off with his sister Larisa Fraley, 16, in a van.
Osage County officials found his sister's body Tuesday morning in that same van.
The new documents said both killings appeared to have happened Monday night.
The document also states that Stanley was picked up from Lake Road near Tall Chief Cove, which is the area near the scene of the second slaying.
The affidavit states two people saw him walking in that immediate area, and those people gave him a ride
Monday evening just after 6.
The affidavit says that Stanley wasn't wearing a coat so the couple gave him one when they dropped him off.
He was wearing the same jacket when he was arrested Tuesday afternoon in north Tulsa.
This was enough for the Osage County District Attorney's Office to file a firstdegree murder charge against Stanley in the death of his sister and it was enough to hold him without bail.
That charge was the only charge filed in Osage County.
Stanley has not been formally charged for the death of his grandmother in Skiatook.
FOX23 spoke with the Tulsa County district attorney then we called the Skiatook Police Department to figure out the hold up on why Stanley has only been charged once.
They explained they have a smaller department that the Osage Sheriff’s Office and a lot of witness statements to collect, and since Stanley is being held without bond in Osage County they are taking their time.
The detective said they don't want to overlook anything that might help them build a case but it looks like the charge could be coming.
The affidavit we picked up in Osage County Friday connects Stanley to his sister's slaying and also points a finger at Stanley in his grandmother's slaying.
It says Stanley stabbed Driskell before leaving the scene with Fraley.
The document then outlines the evidence against Stanley in Fraley's death.
It says she was stabbed multiple times in the neck and that she had wounds that were consistent with defense wounds.
