IDAHO FALLS, IDAHO – August 12, 2015 (Gephardt Daily/ EastIdahoNews.com) – The family of missing Idaho Falls toddler DeOrr Kunz Jr. is working with a private investigator to help find their son, according to EastIdahoNews.com.

Frank Vilt, a retired U.S. Marshal with years of law enforcement experience, said he’s been conducting his own investigation into DeOrr’s disappearance and he believes the two-year-old was kidnapped.

“I feel that he was abducted,” Vilt said in an interview with EastIdahoNews.com Tuesday. “Everything points to an abduction.”

Vilt speaks daily with DeOrr’s parents, DeOrr Kunz Sr. and Jessica Mitchell. He said the couple has cooperated fully with law enforcement.

“I’ve talked to Lemhi County deputies and I’ve talked to Bonneville County,” Vilt said. “The parents are being very forthright and have nothing to hide.”

Vilt has visited the Leadore campground where DeOrr was last seen. He’s also spoken with folks who live near the area and says he shares his tips with law enforcement. Just days ago he learned something he believes may be useful in the case.

“When [the family] went into town the morning after they arrived, they picked a few groceries up and bought some French fries for DeOrr Jr.,” Vilt said. “There was a man who was staring at DeOrr and this made Jessica feel kind of eerie. I’m looking into it.”

Vilt says he has interviewed people registered on the sex offender list who live in Lemhi County and, according to him, all of them were cleared.

The private investigator has set up a national phone tip-line in hopes of finding DeOrr. The public is asked to call (888) 852-6505 with any information on his disappearance.

“I honestly believe in my heart of hearts that these are grieving parents and I want to hope that they feel like I feel, that somebody out there knows something,” Vilt said.
