A person with first-hand knowledge of a man's confession to murdering four missing Pennsylvania men says the man killed them separately after selling them marijuana and then burned their bodies at his family's farm.
The person spoke to The Associated Press on the condition of anonymity because he wasn't authorized to publicly discuss details of the case. The person says a co-conspirator was involved in three of the killings.
The details were provided after one of Cosmo DiNardo's lawyers said Thursday that DiNardo had confessed to murdering the missing men, including a Maryland college student.
Authorities have identified one body. They're working to identify other remains found in the same grave.
DiNardo and his parents met with authorities at a courthouse for several hours Thursday. As DiNardo was led away in handcuffs, he said, "I'm sorry."
