Prosecutors call the day of the murders "one of the worst days in Bucks County history."
After Dean Finocchiaro was killed but before Tom Meo and Mark Sturgis came to Cosmo DiNardo's farm in Solebury, DiNardo's dad pulled into the driveway with his mistress in the front seat.
Jurors heard from that mistress Thursday — the bookkeeper at DiNardo's trucking company —as she testified she saw someone she now assumes was Sean Kratz. At the time, she said she only knew it wasn't DiNardo.
Prosecutors started the day by showing autopsy photos. Forensic pathologist Ian Hood testified to the injuries and what caused the deaths of the three men.
Their families have been in the courtroom, and there were audible sobs as Hood described the gunshot wounds that killed Finocchiaro and Sturgis. He said Meo was shot in the back, likely paralyzed, but it was blunt trauma that killed him as he was run over by a back hoe.
DiNardo pleaded guilty to those three murders and also the murder of Jimi Patrick. He's serving four life sentences in state prison.
Kratz was going to plead guilty, but he backed out at the last minute. It's unusual for murder defendants to take the stand, but Kratz's lawyer said he is expected to testify.
