DOYLESTOWN, PA — The trial for a man accused of helping his cousin kill three young men on a Solebury Township farm in 2017 will begin Wednesday in Bucks County court. Sean Kratz, 22, is charged with homicide in connection with three of the four murders carried out on a farm owned by the family of Cosmo DiNardo.

DiNardo has already pleaded guilty and is serving a life sentence for four murders. However, Kratz rejected a plea deal. Authorities say the victims were killed in three separate shootings, all of which took place on DiNardo's family farm on Lower York Road. Kratz was involved with two of the shootings, authorities allege.

The slayings were connected to three separate drug transactions, the Bucks District Attorney has said.

Jimi Taro Patrick, 19, of Newtown Township was killed first. Two days later, authorities said DiNardo and Kratz killed Dean Finocchiaro, 19, of Middletown Township; Thomas Meo, 21, of Plumstead Township; and Mark Sturgis, 22, of Pennsburg.

Human remains were discovered days later on the farm after a massive search effort by multiple agencies. Authorities say DiNardo buried Patrick in a single grave on his parents' land in Solebury and buried the other three victims in a 12-foot-deep common grave on the same property.

The killings rattled the normally quiet community of Solebury, putting Bucks County in national headlines as law enforcement searched for the missing young men before making the gruesome discovery.

It began on July 5, 2017 when DiNardo picked up Patrick at his Newtown home and took him to the property in Solebury after he agreed to sell him marijuana.

When Patrick came up short with money for the transation, DiNardo took him to a remote part of the property and shot him with a .22-caliber rifle, investigators have said. DiNardo then used a backhoe that was on the property, dug a 6-foot hole and buried him, authorities said. Two days later, on July 7, DiNardo allegedly agreed to sell marijuana to Finocchiaro. DiNardo first picked up Kratz and drove to Finocchiaro's home in Middletown Township.
