What we know

Confession made: Cosmo DiNardo has "confessed to his participation or commission" in the killings of the four missing men in exchange for prosecutors promising not to seek the death penalty against him, DiNardo's defense attorney said. The attorney said DiNardo "did give a full confession and he was very forthright and gave all relevant details that he could."

Remains found: On Wednesday, investigators found human remains on a Bucks County farm owned by the parents of Cosmo DiNardo. At least some of the remains were identified as belonging to Dean A. Finocchiaro, 19, of Middletown, who was among the four missing men. The remains were found buried more than 12-feet underground. DiNardo admitted dumping three of the missing men's bodies in the grave, a source told the Inquirer and Daily News. He is expected to lead investigators to the grave of the fourth victim.

Who is missing: Investigators were looking for four young men, identified as: Mark R. Sturgis, 22, of Pennsburg; Thomas C. Meo, 21, of Plumstead; Dean A. Finocchiaro, 19, of Middletown; and Jimi Taro Patrick, 19, of Newtown. Finocchiaro's remains were identified in the grave found on the farm.

Second suspect: An alleged accomplice of DiNardo's, 20-year-old Sean Kratz, was taken into custody in Northeast Philadelphia, according to law enforcement sources. DiNardo had told investigators there was an accomplice in the killings, a source said.
