The man's body was found Tuesday morning in front of a trailer near Lincoln and Bethel, near Del Rey.
Family members have identified the victim as 36-year-old Jesse Sustaita. They say he is a father of six who worked as a farm laborer and handyman on the ranch where he was found.
Deputies were called out just after 6:00 Tuesday morning after getting a 9-1-1 call.
"At this point and time we are still talking to witnesses and people that reside on this property," said Robert Buenrostro. "It has to do with the last people that he was in contact with and we haven't identified those yet."
Sheriff's investigators say the victim appears to have been shot.
A neighbor told Action News he heard gunfire in the area around 1:00 in the morning, but didn't know it was related to a murder.
