Two brothers were found shot to death Tuesday in a ravine near their family's mobile home in a remote area of Chino Hills, San Bernardino County sheriff's officials said.
Authorities said they received a call shortly before noon from a family member who discovered the bodies of Bryan Gonzalez, 12, and Christian Gonzalez, 10. They were found about 60 feet behind the Gonzalez home, which is on a ranch on Mystic Canyon Drive between Twin Knowles Drive and Via La Cresta.
The boys were pronounced dead at the scene. Autopsies will be conducted, authorities said.
Details about the deaths have not been released, but police were called to the scene after neighbors heard gunshots. The boys' relatives were at home Tuesday and were cooperating with investigators, said San Bernardino County sheriff's spokeswoman Cindy Bachman.
"The initial indication at the scene is that they don't have an outstanding suspect, that this incident occurred with just the two boys involved. However, they have not completely ruled out foul play," Bachman said.
