The witness told police he also discovered a knife missing from his home. The knife matches the knife used to kill Stanley, according to the affidavit.
Police used phone records to determine Baker's cellphone was in the area of Stanley's home when she was killed.
Police found a glove under Stanley's body that contained DNA evidence, along with DNA samples taken from other items in the house.
Baker was arrested Thursday night at a home in northwest Oklahoma City. He is being held without bail at the Cleveland County jail.
