It was probably the Mexican coyotes that buried them. They don’t want to get caught smuggling human cargo.
Some of the coyotes human cargo probably died. They will load illegals in trucks with no air.
>>Teams unearthed remains in trash bags, shopping bags, body bags or without a container at all, according to the Corpus Christi Caller Times. In one burial, bones of three bodies were inside one body bag. In another, at least five people in body bags and smaller plastic bags were piled on top of each other. Skulls also were found in biohazard bags placed between coffins.<<
Mexican coyotes are using body bags and biohazard bags? Not very likely.
