The two Pennsylvania residents accused of killing four young men who went missing last week used a metal tank they called a “pig roaster” to burn some of their victims’ bodies, court documents filed Friday reveal. Cosmo DiNardo and Sean Kratz, both 20, provided detailed accounts of the killings in affidavits filed for their arrests Friday. They face charges including homicide, robbery, and abuse of a corpse for the murders of Dean Finocchiaro, 19; Thomas Meo, 21; Mark Sturgis, 22; and Jimi Taro Patrick, 19. In addition to burning the victims' bodies, the pair also allegedly confessed to using a backhoe to crush one of the men after shooting him, according to The Philadelphia Inquirer. DiNardo said he first killed Patrick after the man didn’t bring enough money to a drug buy, and he later lured the other three men to his family's 90-acre farm to kill them.
