Ricks would not say if the mother was under the influence of alcohol or drugs when she was arrested about 3:30 p.m. at the Olde London Towne Apartments, 5518 NW 23.
The arrest occurred after Oklahoma City police received a call on Dominic Smith's whereabouts.
The investigation was a joint effort by Edmond and Oklahoma City police and the FBI.
Oklahoma City Deputy Police Chief Johnny Kuhlman called the investigation "a lot of old-fashion police work."
"When you knock on doors, you gain information and a lot of that information led to someone making the phone call and the arrest was made," Kuhlman said.
Six of Edmond's 15-member detective force had been assigned full time to finding the girl.
"We literally spent hundreds of hours on this particular case," Ricks said.
"It would not have worked without all of us spending these hundreds of hours to have a successful conclusion."
