ALTUS, Oklahoma - An Altus couple accused of seriously hurting their baby have been returned to Oklahoma following their arrest last month in Arizona.

The Jackson County Sheriff's Office says 18-year-old Keilani Gomes and a 17-year-old male were taken into custody in Mesa, Arizona on a charge of assault and battery by force likely to produce death.

That charge was filed in November 2016.

The child, now nine months old, was taken to the hospital with a severe head injury and fractured vertebrae in both the neck and ribs. 

Doctors told Altus Police, the injuries are consistent with non-accidental trauma, which means it could have been done on purpose.

The baby remains in critical condition at OU Children's Hospital in Oklahoma City.

Court records show the couple has a court appearance set for February 2nd.
