The surviving family members of a mass shooting in Tehama County are taking legal action against the "ghost gun" industry. Complaints filed in Superior Court of Orange and San Bernardino County by the Brady Legal Alliance center on 13 suppliers of mail-order gun parts. Two of these ghost gun kits were used in a 2017 massacre in Rancho Tehama that killed six and wounded many more. Ghost guns get their name because the parts lack serial numbers or paperwork, which can evade Brady Background Check laws.
