A revelation by the defense during the sentencing of 18 year old Parrish Bennette for the 2011 killing of 14 year old Yashawnee Vaughn tore  the scars off a family's pain.

Bennette sat in the Multnomah County courtroom stone-faced - sometimes grinning - as the judge laid out the case.  How Bennette - then 16 - killed Vaughn and hid her body on Rocky Butte.

The prosecution detailed the plea deal - 18 years for manslaughter - but when defense attorney Thomas McNair told the court he'd delaying telling police where Vaughn was buried her mother - Shaquita Louis - wailed. "I could've been able to put my daughter to rest the right way.  I didn't even get to tell my daughter's body  I love her.  For them to sit there and let my baby lay out there like that......that hurts."

Vaughn's great aunt - Marsha Hayes - says Bennette's never shown any remorse for what he's done. 

The baby-faced boy with the icy heart has never said why he killed Vaughn and has always claimed it was an accident.

Bennette will be out of prison when he is 34.
