An endangered Peninsular bighorn sheep died after becoming entangled in concertina wire at the US-Mexico border in Jacumba Wilderness. - The ram was found by wildlife biologist Christina Aiello on June 3, 2026, with its horns and legs trapped in the wire.
- Conservationists had warned CBP about risks, but requests to remove wire and build animal passages were denied. - Residents report more wildlife near homes, some with injuries, since wire installation.
- CBP declined to comment; CDFW called the death a tragic reminder of border wall risks.
