Authorities found the body of a 16-year-old girl near Skiatook Lake early Tuesday.
Skiatook Police say the death is connected to a murder scene Monday at a home in Skiatook.
We're told Skiatook police responded to a house on East Oak Street and South C Street Monday around 5 p.m. where they found Esther Driskell dead.
Investigators say the woman in her 70s was repeatedly stabbed and there was no sign of a forced entry.
Skiatook police tell KRMG 19-year-old Michael Devin Stanley was taken into custody Tuesday as a suspect.
He's the half-brother of the young girl, 16-year-old Larissa Fraley, and the great-grandson of Driskell.
Detectives are looking into a motive.
