May 17 (UPI) -- A Pennsylvania judge has sentenced a man who killed four people and buried them on his family's property to life in prison.
Judge Jeffrey Finley ordered Cosmo DiNardo to four life sentences Wednesday, after he pleaded guilty to the deaths, the Bucks County District Attorney's Office said.
"I want the four families to know I am so sorry," DiNardo said in court. "If there was anything I could do to take back what occurred on those days, I would.
"I hope that they find some peace in knowing that I'm just genuinely -- I can't even come to terms with what occurred. I'm sorry. Sorry."
Finley called the apology "false and insincere," and sent him to prison.
DiNardo, 21, confessed last year to killing Dean Finocchiaro, 19; Thomas Meo, 21; Mark Sturgis, 22; and Taro Patrick, 19, in exchange for dropping the death penalty.
The deaths were dubbed the "Solebury slayings," after the southeast Pennsylvania town in which they occurred.
DiNardo's cousin and accused co-conspirator, Sean Kratz, rejected a plea offer from prosecutors.
Prosecutors say they will seek the death penalty for Kratz, who faces charges in three of the deaths.
In addition to four counts of first-degree murder, DiNardo's guilty plea included charges of robbery, abuse of a corpse, conspiracy, possession of instruments of crime and illegal firearms possession.
The DA called DiNardo "a turbulent son of privilege," who admitted "luring the victims" to his parents rural estate to sell them marijuana.
