Santa Fe police arrested the parents of a 2-year-old boy after doctors said the child was so severely abused last month that his legs might have to be amputated.

Authorities say 26-year-old Anthony Apodaca and 20-year-old Jennifer Stephenson each have been charged with one count of child abuse.

The couple was arrested Wednesday, two weeks after taking their son to a Santa Fe hospital.

Police Sgt. Louis Carlos says the boy sustained leg wounds that appeared to have been caused by a ligature of some kind.

According to a court affidavit, Apodaca told police the boy apparently tried to climb a 4-foot-high chest that fell on top of him and pinned his legs against a bed rail. Stephenson claims she was asleep and didn't hear anything.

The boy is hospitalized in Albuquerque.
