HONOLULU -- An Ewa Beach couple on Wednesday entered pleas in a case of abuse so severe, prosecutors said children suffered in a "house of torture."

Prosecutors said the couple abused five related children that were in their foster care.

Barbara Kalama pleaded guilty to endangering the welfare of a child and child abuse. Her plea agreement includes five years of probation and one year in prison.

Her husband, Gabriel Kalama, pleaded no contest to assault and abuse.

Prosecutors said that Gabriel Kalama forced one child to eat another child’s feces, that he taped a child's hands together and exploded fireworks between the child’s hands and that he beat two children with a bat.

Gabriel Kalama faces five years in prison, but the judge said she would consider lowering that to two years if he testified truthfully against his mother-in-law, Rita Makakau.

Prosecutors said Makakau, the children’s aunt and Barbara Kalama's mother, used knives and cans of food to beat the children.

The children have been placed into foster care. They are doing well, prosecutors said.

One reason that the children’s abuse was never detected was because they never went to see a doctor for their entire lives, prosecutors said.
