Amarillo, TX - An update now on the little boy found dead inside a cooler in an Amarillo attic over the summer.
Potter Randall Special Crimes says all the tests are back on Miguel Nunez, who was about eight-months-old when he disappeared in 2004.
A forensic pathologist said the body was too badly decomposed to determine what killed Nunez.
His father, Robert Nunez, remains behind bars on an aggravated perjury charge, with a bond of $100,000.
He's accused of lying to a Potter County Grand Jury back in April, saying his son was still alive.
