On May 16, 1987, two teenaged models and their elderly female chaperones were reported missing after they failed to return from a trip to Lake Tahoe, on the California-Nevada border, for production of an anti-drug video program. Missing were: Maybelle Martin, 69, operator of the Showcase Finishing and Modeling School in Reno, Nevada; her friend Dorothy Walsh, 67; model Alecia Thoma, 14, of Reno; and model Monica Berge, age 12, from nearby Sparks. A three-day search by fifty law enforcement officers, including agents of the FBI, centered on Lake Tahoe, where local girls had complained of a "weird" man who tried to recruit them for anti-drug video projects. One of the girls was suspicious enough to record the man's license plate number, a detail which led investigators to the rural home of Herbert Coddington. The name was a familiar one to officers throughout Nevada. Coddington had worked at two casinos in Las Vegas during 1980, and a warrant filed in Douglas County charged him with a cheating scam in April 1984. Arrested in Las Vegas, he had been released on $500 bail and the case was still pending. On May 18, 1987, federal agents armed with warrants raided Coddington's mobile home, freeing Thoma and Berge from a boarded-up bedroom where they were held captive. The bodies of Maybelle Martin and Dorothy Walsh were found in an adjoining room, bound up in plastic garbage bags. On May 20, Coddington was arraigned on two counts of murder, with five other counts charging rape and acts of deviate sexual abuse against the teenaged victims . With their man in custody, authorities began to search his background, and they soon discovered links with yet another crime. In August 1981, 12-year-old Sheila Keister had been kidnapped , raped and strangled in Las Vegas, her body discarded beside an unpaved road on Sunrise Mountain, east of town. Upon examination, prosecutors charged that dental casts obtained from Coddington matched bite marks on the dead girls body, and another charge of homicide was filed on July 22, 1987.
