The person of interest in the disappearance of four young men in Pennsylvania says he killed the men. Cosmo DiNardo's lawyer Paul Lang said yesterday that DiNardo told investigators where they can find the bodies. In return for his confession, the district attorney promised not to seek the death penalty against the 20-year old. The Associated Press reports Dinardo is a drug dealer. He killed the victims after he felt cheated or threatened during three drug transactions, and then burned their bodies at his family's farm in suburban Philadelphia, a person with firsthand knowledge of his confession said. DiNardo is currently in custody on charges of stealing a car belonging to one of the missing men. Investigators found the remains of Dean Finocchiaro in a grave on a farm belonging to DiNardo's family. Finocchiaro and three others all disappeared last week.
