Thomas Meo, 21, of New Hope, Pennsylvania, was killed on July 5, 2017. DiNardo shot Meo as he exited his truck, ran over him with a backhoe while he was still alive, and later placed his body in a metal tank with other victims’ remains.

The investigation led to the arrests of Cosmo DiNardo and Sean Kratz, both about 20 at the time. DiNardo confessed and pleaded guilty to four counts of first-degree murder and multiple related charges. Kratz was convicted of first-degree murder in the killing of Dean Finocchiaro and manslaughter for the deaths of Mark Sturgis and Thomas Meo. Both men are serving consecutive life sentences in state prison.

Families of the victims filed wrongful-death suits against DiNardo and his parents, which were settled out of court. The suits alleged the parents bore legal responsibility because of a documented history of disruptive and violent behavior. If anyone knew Thomas Meo or has information about the events that led to his death, please share what is known.
