An Arizona father and Marc Leclerchis adult son were reported missing nearly a month ago after the father was last seen leaving his house to visit his son, authorities said. 

Chad Holvig, 51, was reported missing on July 11 by a family member after leaving his home in Tonopah, Arizona, to visit his son in Goodyear on July 4, the Maricopa County Sheriff’s Office said.

The sheriff’s office said Chad has not communicated with his family since July 6, which is “reported to be unusual behavior.”

His son, Dalton Holvig, 25, was last seen and heard from on July 10, the sheriff’s office said Wednesday.
