Five children -- one with cancer-- locked in a dark bedroom described as a "dungeon."

Police said the children had no food, no toilet, routinely beaten and threatened with a gun, sometimes for more than a day.

Police said the parents, Sarah and Yenier Conde, of these children now ranging in ages 6 to 11, are facing charges of abuse and unlawful imprisonment.

It dates all the way back to 2009 when CPS first investigated claims of improper supervision and physical neglect. They reported the home was filthy ---soiled diapers throughout the hallway, dog feces throughout the home.

However, Sarah Conde's best friend said these conditions are an exaggeration.

28-year of Sarah Conde is in jail tonight. Yenier has not been taken into custody. Yenier has two previous charges of child abuse and unlawful imprisonment in October 2017. Both those were dismissed.

"They don't deserve to be looked at like that because they both are very good people," said Heaven Peterson, Sarah Conde's best friend.

Peterson even lived in the house with them for several months, she said she didn't see what police and Child Protective Services are calling abuse and neglect.

Documents show that in 2013, their five-year-old wasn't potty trained and sent to school in a soiled diaper, and no extras were sent.

Even more shocking, in May 2017 all five kids told a CPS worker that they had been locked in a room for "a bunch of days."

The kids told the same story again on June 3rd, 2017 to a Lansing Police detective.

Peterson said they would have short timeouts, not days of isolation.

"They were always outside, they used to come over and spend the night, they were always out here," said Peterson.

Reports show on May 12th, 2017 the children told CPS.

The parents would put the gun to their heads, and threaten them.

Several reports dating back to 2009 show that the home had an odor of feces. When Peterson was living with them she didn't think so.

"It was always hectic, but it seemed like we cleaned all the time," said Peterson.

Numerous reports from CPS investigators said children were described as filthy.

Peterson told me that wasn't the case when she had eyes on them.

"The kids were perfect, they were normal kids, they were a little busy and a little crazy," said Peterson.

Their five kids are currently in foster care.
