A second arrest has been made in three mutilation killings in the San Luis Valley that came to light when the victims' remains were found in a remote area in November. An affidavit obtained by The Gazette shows that 38-year-old Francesco “Poncho” Ramirez was arrested in Pueblo on Dec. 11 on federal weapons charges. In a search of his car, police found a gun, methamphetamine and heroin. The affidavit also states that Ramirez is suspected of being an accomplice in the killings of at least three people whose remains were, according to a confidential informant, mutilated and driven around the San Luis Valley.
