Robert Frost and Wally Kasza, two Area 51 workers, died in the 1990s after illnesses their lawyer linked to alleged toxic-waste burning at the base. Jonathan Turley, the lawyer who sued the US government for Frost's widow, Kasza, and other workers, said in 1999 that aliens played no part.
President Bill Clinton then signed an order shielding classified details of the base's waste. By 1999, the families still did not know what the men had breathed. Their case is back in the news as a former US Army sniper's alien tale, with no named victim, spreads online.
