The 47-year-old victim was found shot to death in a travel trailer on Avenue 400 near Road 40, just east of Kingsburg.
Officials say 34-year-old Gerardo Ortega lived on the same property as the man and began searching for him early Friday morning.
Investigators tracked him down in Reedley, where they discovered an assault rifle in his car that is believed to be the gun used in the deadly shooting.
Ortega will be booked into the Tulare County Adult Pre-Trial Facility.
This is a developing story.
