The news of the death of Bachelorette contestant Julien Hug was a shock to his former cast mate and friend Kiptyn Locke, who exclusively told RadarOnline.com that it was “sad, devastating news.”

Hug, 35, was found dead Wednesday in a remote area near Palm Springs and reports claims that his body was identified by this father.

Riverside County Sheriff’s Deputy Melissa Nieburger confirmed the news, “A body was found in a quite remote area of rugged terrain, well off the road. This is an area you would need to hike to.”
