Prior to John Gardner's sentencing on Friday, court officials released impact statements on Thursday from Amber's father, Maurice "Moe" Dubois, and his girlfriend, Rebecca Smith, that will be read in court.
Gardner pleaded guilty on April 16 to the murders of 14-year-old Escondido High student Amber Dubois and Poway teenager Chelsea King, 17. Both of their bodies were discovered in shallow graves after the killings.
In Maurice's statement, he ponders who bears the most responsibility for the death of his daughter. (The following statements are quoted exactly as they appear in the documents unless otherwise noted -- Ed.)
"I cannot help to ask on behalf of my family, Who is at Fault here? Is it this cold heartless monster, is it the failures in the law enforcement system, or perhaps it is even all of us who have not forced and held accountable, the people and the organizations who are supposed to protect us from these predatores and whom are not."
Amber's father then goes on to share his hope that prison system administer "justice" to his daughter's killer.
"Now with our last hope for justice, we depend on the prison community to slowly and painfully cause his remaining days on this earth to be a living nightmare," Dubois writes.
Smith, too, crafted a personal picture of the tragedy to be shared with the court on Friday.
"On March 6th, 2010 we were told she had been found," Smith wrote. "This was the worst day of my life.... After [Amber] was located people believed that we would have closure. This is not the case.... Our lives have been changed forever and nothing can change this. However you can change the fate of many more lives by securing Gardner in prison forever.
Gardner is due in court at 1:30 p.m. Friday to be sentenced in connection to the case. Prior to entering his guilty plea, his attorneys negotiated a deal with prosecutors for a sentence of life without the possibility of parole.
