Family members of the victims were brought into court through a side door so they could watch 20-year-old Cosmo DiNardo, of Bensalem, waive his preliminary hearing.
DiNardo is facing charges of conspiracy, murder, abuse of a corpse and robbery in connection with the deaths of Dean Finocchiaro, Jimi Patrick, Mark Sturgis and Tom Meo.
Their bodies were discovered in July buried on a DiNardo family farm in Solebury.
"They didn't get to see him face to face, but they certainly saw him and he appeared to be a cowardly individual on that screen, on that video in prison where he belongs," Finocchiaro family attorney Tom Kline said.
Twenty-year-old Sean Kratz of Northeast Philadelphia, DiNardo's cousin and alleged accomplice, did not waive his preliminary hearing.
Some family members wept when they listened to details of how the four young men were allegedly shot by DiNardo, who then moved their bodies with a backhoe, burned and buried them.
"I wish there was another word that could actually describe what happened, that's a very good word to describe what these four boys went through," Assistant Bucks County District Attorney Gregg Shore said.
Detective Martin McDonough who took a statement from Kratz says the suspect told him he and his cousin went out for cheesesteaks after the killings.
"Kratz indicated in his own words it was a massacre," Meo family attorney Robert Mongeluzzi said. "They went out for a post-massacre cheesesteak meal. It is unconscionable and outrageous."
Kratz is charged with killing three of the men.
"You heard what I heard and what we heard is my client places himself at the scene of these killings and that is all that he said so far," Kratz's attorney Craig Penglase said.
The defense presented no evidence or argument at the hearing.
Kratz and DiNardo are both being held until trial.
Their next court appearance is October 6 when they will both be arraigned.
