The two men charged in the murders of four men on a Bucks County farm are pleading not guilty. Cosmo DiNardo and his cousin, Sean Kratz, are charged with killing the men whose bodies were found buried on DiNardo's parents farm in July. Both were in a Boylestown courtroom yesterday to enter their pleas. The Bucks County DA's Office says as long as DiNardo continues to cooperate it will honor an agreement not to seek the death penalty against him.
