Sean Michael Kratz has been arrested and charged by the Bucks County District Attorney’s Office for being an accomplice in the mysterious murders of four men who were reported missing last week.

Less than 24 hours after Cosmo DiNardo confessed to the murders of the men, authorities said they took a second “person of interest” into custody. That man turned out to be Kratz, who was charged with aiding in the murders of the men Friday.

The remains of the four men, 19-year-old Dean Finocchiaro, 22-year-old Mark Sturgis, 21 year old Thomas Meo, and 19-year-old Jimi Tar Patrick were found on a property owned by the DiNardo family in Solebury Township.

Police say that Kratz and DiNardo killed the men and tried to burn their bodies in a pig roaster on the property. After that, they buried the bodies in two separate graves.

DiNardo was charged Friday with counts of conspiracy, homicide and abuse of a corpse.

Bucks County District Attorney Matthew Weintraub said that the remains were located in a makeshift grave that was almost 13-feet deep on the property. It’s believed that DiNardo and Kratz used construction equipment from his father’s business to dig a hole on the 90-acre property.

According to The Philadelphia Inquirer, the investigation shifted to an address in Northeast Philadelphia, where Kratz lived.

Police told the newspaper that they performed a search on an address in the area and took Kratz into custody. He’s since been charged alongside DiNardo for taking part in three of the killings.

Read his list of charges in the document below:

According to the Inquirer, Kratz was out on bail for separate charges for a pending theft case in Philadelphia. In the first instance, he was accused of committing burglary, criminal trespassing, theft, receiving stolen property and others. Those stem from a December 2016 incident and he posted 10 percent of his $10,000 bail in March to be released.

The newspaper reported that his latest hearing in the matter was rescheduled because he “had medical issues.” It added that in June 2016, surveillance video caught him and another man breaking into a property and stealing lawn equipment valued collectively at around $1,000.

In February, Kratz was arrested for breaking into a home of a witness in the burglary case and stealing jewelry. He was also charged in December 2016 with retail theft.
