HURON, Ohio -- The Huron County couple accused of abusing their adopted children faced a judge on Wednesday. The couple, who is fighting for custody of their adopted children, also faced their biological children, NewsChannel5 reported.

Michael and Sharen Gravelle were arraigned on child endangerment charges. The couple were also charged with falsifying adoption applications and lying under oath when being qualified for adoption funding.

Last year, officials found cage-like structures the Gravelles made for the children to sleep in.

The Gravelles deny abusing their adopted children, ages 1 to 15, saying the beds enclosed with wood and wire and equipped with alarms were necessary to protect the youngsters, who suffered from various psychological and behavioral problems.

The couple has 11 adopted children.

Michael Gravelle's biological son, Jesse, testified for the prosecution that he was a teen when his father married Sharen and became abuse.

He added he was kicked out at that time.

Jenna Gravelle, 31, also testified on behalf of Huron County's case to strip their father and stepmother of custody. The hearing could continue through the end of the week.

Jenna said her father and stepmother provided little food for her and her brothers and that the couple charged the teens money to live in their home.

"I was miserable," Jenna Gravelle said, describing minimal food, little privacy and alleged "inappropriate touching" by her father that began when she was 6 or 8.

"I felt like a prisoner," she said. Her voice cracked occasionally, and at times she began breathing very heavily when she talked about the alleged abuse. (Read More) about her allegations.

Jesse Gravelle testified that his father sat him and his brother down when they were youngsters after Jenna left home and "told us that he had inappropriately touched her."

"He didn't indicate how long or any details, just that he had inappropriately touched her," Jesse testified.

He also said that his father had entered counseling "for child abuse" and, asked if his father had completed the counseling responded, "I do not believe he did."

The Gravelles' trial is set to begin in September.

If convicted, they would face one to five years in prison and a maximum fine of $10,000 for each of the 16 counts of felony child endangering.
