An investigator hired by the family made comparisons to Casey Anthony while suspecting parents of murder.
The mystery of 2-year-old DeOrr Kunz disappearance has baffled authorities for more than a year.
The boy disappeared while on a family camping trip in the Salmon Challis National Forest in Idaho last July. The forest is a popular vacation spot that spans 4.3 million acres.

The story is featured on the cover of the upcoming issue of People magazine, on newsstands Friday. The parents have stated that they left the child with another family member when they went exploring and that when they returned to the their campsite the child had disappeared.
As the days turned into months with no trace of the child, his parents said they believed that the child may have been he was abducted.
In January came the bombshell that DeOrr's parents were named as suspects in the little boy’s disappearance.
Philip Klein is a private investigator hired by DeOrr's family when the toddler first went missing.
He says they fired him when he started to suspect them. He says Jessica Mitchell reminds him of Casey Anthony, who was acquitted of killing her child in 2011.
“We found that over time their statements were less than truthful,” he told Inside Edition. “This thing mirrors the Casey Anthony case. Jessica has a long history of erratic behavior. The child was getting in her way, she was not interested in raising a child.”
The boy's parents, Jessica Mitchell and Vernal Kunz, say they went for a walk, leaving the toddler in the care of his grandfather, but when they returned to camp, the boy was gone.
Lemhi County Idaho Sheriff Lynn Bowerman told EastIdahoNews.com: “We searched every place a child could fall into or hide in or fit in and we found nothing. Absolutely nothing.”
Some wondered whether a wolf or a bear snatched the little boy.
“We don't believe it's an abduction – either human or animal," Lemhi County Sheriff Lynn Bowerman told People.

Last week, Jessica shocked everyone with the Facebook announcement that she had split from DeOrr's dad and married a man she met six weeks ago.
“Her behavior pattern is anything but a grieving mother,” Klein said. “He is anything but a grieving father. They are moving on with their lives.”
The parents of the boy have not been charged. They say they have cooperated with police and are completely innocent.
Allen Browning represents the missing boy’s parents. He told Inside Edition the parents do not know how their son disappeared but it could even possible that a wild animal may have snatched little child.
"About two months ago I got a call from someone in the area that had been in the same campsite the week before and said there was a huge bald eagle menacing his dogs," he told Inside Edition. "There is more of a chance of that happening than the mother and father abducting him."
