DeOrr Kunz's grandmother says today is a day that will 'haunt the rest of our lives'

IDAHO FALLS -- Four years ago today DeOrr Kunz Jr. disappeared while on a camping trip in Lemhi County.

The Idaho Falls two-year-old vanished July 10, 2015, at the Timber Creek Campground with his parents, Jessica Mitchell and Vernal DeOrr Kunz. DeOrr's great-grandfather, Robert Walton, and Isaac Reinwand, a friend of Walton's, were also on the trip.

There has been no sign of DeOrr since that day, and nobody has been charged in connection to his disappearance. Mitchell and Kunz were named as suspects in January 2016 by former Lemhi County Sheriff Lynn Bowerman but they have never been arrested.

While no major developments have occurred in the case over the past year, the Lemhi County Sheriff's Office closed part of the Timber Creek Campground June 28 to July 1 for a search. Sheriff Steve Penner declined to comment about what crews did at the site but said investigators will follow-up in the area "as environmental conditions change."

Trina Bates Clegg, DeOrr's grandmother and Mitchell's mother, agreed to speak with EastIdahoNews.com about the anniversary of her grandson's disappearance and where the case stands today.
