Bourgeois, family members and friends spent days looking for Hebert on their own at the lake. Hebert’s family says Blue Heron Park was one of his favorite places.

Hebert walked away from a living facility for people with brain injuries.

The volunteers used a drone, inflatable kayak and bloodhounds to look for Hebert and found one of his boots.

“Really glad, just relief today. We have this drone. I know it’s him. Of course, we have to have a coroner, but some relief. We can finally as a family stop searching, drudging water, calling on friends and give us some closure and honor his life,” Bourgeois told CBS4 on Saturday.
