In an attempt to finally put the death of then six-year-old Peter Boy Kema, his siblings are suing. They want the people responsible held accountable.

Peter Boy's sisters and brother are suing the boy's father, Peter Kema Senior, mother Jaylin Kema, the state and department of human services. 

The family filed a wrongful death lawsuit Wednesday. 

In 1997, Peter Boy's parents claimed he disappeared. 

It wasn't until about 20 years later when both parents admitted to being involved with his death. 

Kema Senior now admits he burned Peter's body and dumped his bones in the ocean.  

Court documents reveal an extensive list of physical abuse Peter Boy and his siblings endured for years.

It eventually led to foster care placement.  

But according to the family's attorney, despite multiple red flags, the children were returned to their parents. 

"The state decided that it would support his reunification with his family and the termination of the protective proceedings. These parents never cooperated with all of the guidelines that were set up for them to become better parents to become knowledgeable about childcare to deal with substance abuse issues to deal with behavioral issues and severe psychological problems," Randall Rosenberg, attorney, Peter Kema Jr. Estate said. 

A few months before Peter Boy went missing, court documents show it took the department more than two months to report that Peter boy's father broke his arm and forced him to eat dog feces.
