LAS CRUCES, N.M. - A woman and her boyfriend have been arrested in the U.S. after police found an 8-year-old developmentally disabled girl locked in a wooden cage while the rest of the family went to a movie.

The Las Cruces Sun-News reported Monday that officers checking on the girl's welfare found her in the cage the size of a crib.

Authorities say 33-year-old Cindy Patriarchias and 37-year-old Edmond Gonzales of New Mexico remained in custody Tuesday after being arrested Friday.

Patriarchias is charged with negligently causing child abuse, and Gonzales with negligently permitting child abuse. Court records indicate they appeared in court Monday but haven't yet entered pleas.

A police spokesman says Patriarchias has been trying to adopt the girl.
