The remains of two women and a young girl who went missing in 1992 were positively identified Thursday by the state medical examiner's office.
The identities of Wendy Camp, Lisa Kregear and Cynthia Britto have been confirmed, said Amy Elliott, medical examiner's spokeswoman.
The trio had been missing since May 29, 1992.
Camp, 23, Kregear, 22, and Britto, 6, disappeared after leaving Oklahoma City on a trip to visit Camp's son, who lived in Shamrock with his father, Chad Noe.
Their skeletal remains were found in April in a grave in northeast Oklahoma on property that once belonged to Noe's grandmother and uncle, authorities have said.
The uncle, Grover Prewitt Jr., is charged with being an accessory to first-degree murder after the fact. He is accused of helping his mother, Ida Prewitt, and other family members conceal the bodies in 1992. He has pleaded not guilty.
Ida Prewitt died in 2011. No one has been charged directly in the deaths.
The cause and manner of all three deaths are still being determined, Elliott said. The autopsy reports have not been completed, she said.
