Webb's continuing reporting also triggered a fourth investigation. The first article in "Dark Alliance" that discussed the failure of law enforcement agencies to prosecute Blandón and Meneses had mentioned several cases. One of these was a 1986 raid on Blandón's drug organization by the Los Angeles Sheriff's Department, which the article suggested had produced evidence of CIA ties to drug smuggling that was later suppressed. When Webb wrote another story on the raid evidence in early October, it received wide attention in Los Angeles. The Los Angeles Sheriff's Department began its own investigation into the "Dark Alliance" claims.
