On Friday, detectives arrested 35-year-old Tonia Michelle Powers and her live-in boyfriend, 34-year-old Todd Louis Lanford.
Lanford is charged with assault on a child under 12 years old, malicious maiming, felony child abuse afflicting serious injury, assault by strangulation and communicating a threat.
Powers is charged with aiding and abetting a felony and accessory after the fact.
Investigators learned of the abuse after receiving an anonymous complaint.
The child suffered extensive bruising all over his body, contusions on the forehead, eyes, neck, arms, legs and torso. He also was cut along the pelvic area and suffered injury to his genitalia.
The child is in the custody of the Department of Social Services, and he will remain there until the investigation is complete.
Lanford is being held under a $35,000 bond. He is scheduled to appear in court today. Powers was released from jail shortly after her arrest. She is also expected to appear in court today.
