WALNUT GROVE, Calif. — Update:

Martin Chavez, 27, and Martitsa Guerrero, 26, have been arrested in connection to the death of a man investigators believe was set on fire. The victim has not been identified. 

Original story:

The Sacramento County Sheriff's Department have detained three individuals related to this investigation.

Around 8 a.m. Monday, Aug. 26, Sacramento County Sheriff's Department Lt. Dan Donelli said the Walnut Grove Police Department alerted the Walnut Grove Fire Department of a possible vegetation fire at Bailey Ranch, 14633 Isleton Road.

Upon arrival, the fire department found a shed on fire. However, not too far from the shed, fire department personnel found a man suffering from "severe burns."

“It appears that a crime was committed,” Donelli said.

The victim was taken to a hospital in critical condition. Just after 4 p.m., the sheriff's office told ABC10 the victim had died. Deputies have not said if the victim lived or worked on the ranch. 

Not far from the shed, law enforcement found a white pickup truck parked off the road. It may “possibly be connected to a person or persons” from the first crime scene.
