COEUR d'ALENE - Two Post Falls foster parents who are accused of abusing two children and conspiring to conceal evidence of the treatment subjected at least one of the children to ice baths, according to just released indictment documents.

Amber M. Clark, 28, and Jeremy M. Clark, 36, each were indicted by a Kootenai County grand jury on two counts of felony injury to a child, conspiracy to conceal evidence of the abuse, and perjury.

They were arrested and booked into Kootenai County jail last week but were released on bond.

Indictment documents acquired by The Press said the alleged abuse by the couple included "inflicting ice baths" on a boy, who was 4 or 5 years old at the time.

The boy allegedly was abused by the couple in December 2007 and January 2008.

The indictment also said the couple inflicted injuries to his body and head.

Kootenai County Prosecutor Barry McHugh and Post Falls Police Chief Scot Haug couldn't immediately be reached for comment on Friday to discuss the indictment documents.

The Clarks also have been implicated in the death of 2-year-old Karina J. Moore in January 2009. Moore was a foster child placed in the Clarks' care by the Idaho Department of Health and Welfare.

At the time, then Post Falls Police Chief Cliff Hayes said, "The baby was at the bottom of the stairs when we arrived. The explanation was that (Karina) fell down the stairs."

He said Amber Clark reported being on the couch "and recognized the likelihood of the child falling."

She told investigators that "by the time she turned the child was at the bottom of the stairs," Hayes said.

The indictment said the Clarks caused or inflicted injuries to her head or permitted the injuries to occur.

Also, and not previously reported, the documents accuse the couple of "causing an elevated sodium level in the body of (Karina) or by permitting" that to occur.

The documents also said the Clarks were responsible for "causing the child's body temperature to drop under 96 degree or permitting the same to occur; or by withholding medical care" for her.

The indictment accuses both Jeremy and Amber Clark of "intentionally or with reckless disregard for the safety of another person, inflict great bodily injury upon Karina J. Moore," injuries which ultimately caused her death.

The seven-page indictments filed for both Jeremy and Amber Clark list for comparison the various statements they gave investigators looking into Karina's death.

In March 2009, Jeremy Clark told a detective that when he came inside their home, "Amber was reaching to grab Karina because she was trying to catch her from falling the last part."

About two months later, he testified he was outside when he heard "something hitting something on the floor" and he then entered the house and saw his wife down by Karina at the bottom of the stairs.

In January 2009, Amber Clark called 911 and reported that Karina "had fallen down the stairs a few times in the past, and she just did it again, and she is not breathing normally."

A couple days later, she told a detective she saw Karina "hit head first" at the bottom of the stairs on the hardwood floor.

She told investigators she saw Karina do a full flip as she fell.

Then days later, she told a detective that she saw Karina's "body do like a full like [sic] she landed on her neck type thing, and fell flat on the ground."

Karina's mother, Samantha Moore, has been on record saying she doesn't believe her death was an accident.

The Spokane County Medical Examiner's Office ruled the case a homicide, citing "blunt force head injuries."
