Police are looking for a Grantsville father of five and a new grandfather after he disappeared on Friday.

Family members claim that Brian Hayes, 45, departed for work at 7:30 a.m. on July 15 and that they last saw him. They claimed that because he has turned off his phone, they are unable to contact him.

Authorities are concentrating their search efforts in the area because they think Hayes headed to Heber City.

The Mirror and Crystal Lake regions, as well as other isolated locations where Hayes may have traveled, are currently under search. On ATVs, members of the community have been joining the hunt to assist in any way they can.

“We get a little bit emotional, but he has so many friends that are coming here and helping us; just gives us more strength and confidence,” said Jeff Hayes, Brian’s father. “We are just going to take it a day at a time and see what we can do.”

Hayes has a white and grey beard and is 5 feet 10 inches tall. He weighs 350 pounds. Flyers distributed in response to his disappearance state that Hayes was last seen sporting a polo shirt and pants.

The family provided an update late Tuesday night, stating that they had discovered Hayes’ truck abandoned in Ashley National Forest. Although they have requested search and rescue, they have still not located him.
