A pretrial hearing was completed Monday in the case of Sean Kratz.
Prosecutors say he helped his cousin, Cosmo DiNardo, kill four young men, back in 2017, then bury their bodies on DiNardo's family farm in Solebury Township.
DiNardo is already serving a life sentence, but Kratz rejected a plea deal.
His murder trial is scheduled to begin on Wednesday.
It's expected to last one week.
