SEASON 4, EPISODE 403 - When the skeletal remains of a man found in a subway tunnel are identified as a miner who disappeared in 1947, Rush and Valens believe that he may have been murdered. In 1947, the rumor mill was abuzz with rumors about why the man went missing. Maybe it was because of his attempt to unionize his fellow miners or because of his scandalous, public love affair. There was a long list of suspects, including the owner of the mining company, who wanted to stop the impending strike, and a fellow miner who wanted nothing to do with fighting for anyone's rights. Meanwhile, Rush's boyfriend, Joseph (recurring guest star Kenneth Johnson), tells Rush that he loves her.
