DOYLESTOWN, Pa. (AP) - One of two cousins has pleaded guilty to murder charges in the gruesome killings of four young men whose bodies were found buried on a suburban Philadelphia farm.
Cosmo DiNardo faces life in prison under the terms of the deal reached Wednesday.
His cousin, Sean Kratz, is expected to plead guilty to charges related to his involvement in the deaths of the men, ages 19-22, last July.
The 21-year-old DiNardo pleaded guilty to charges including first-degree murder, conspiracy, robbery and abuse of a corpse.
DiNardo's lawyer has said he'd plead guilty to avoid the death penalty.
DiNardo was once committed, but lawyer Fortunato Perri said mental health professionals weren't sure they could present an insanity defense.
A woman in the packed courtroom gallery wept as DiNardo entered his plea.
