( CNN ) -- The bodies of three men have been found in shallow graves in eastern Ohio , all of them believed to have been killed after answering a Craigslist ad to work on a cattle farm , according to authorities . The Summit County medical examiner 's office on Saturday identified one of the victims as Timothy Kern of Massillon , Ohio . The 47-year-old 's death , caused by `` gunshot wounds to the head , '' was ruled a homicide , the office said in an audio recording . A phone call led police Friday to Kern 's body in a shallow grave behind an Akron mall , authorities said . Multiple law enforcement authorities , including FBI officials , have tied Kern 's death to a wider investigation into the two other killings . In his last Facebook posting , dated November 10 , Kern wrote : `` Just got one of the strangest job offers . A good offer but strange . The job is to watch over 680 acres south of cambridge . Odd jobs and such but mainly just secure it . Trailer , utilities , salary . Drawbacks ? No cell phone service , kids are up here , and i have to move this Sunday . '' Meanwhile , the body of a `` white male '' was also discovered Friday `` in a shallow grave in Stock Township , '' about 120 miles south of Akron , Noble County Sheriff Stephen Hannum said in a statement . The sheriff did not respond to calls Saturday from CNN . But Hannum said earlier this month that there are `` two suspects in custody '' in the case . Michael Rafferty told CNN affiliate WJW that his 16-year-old son Brogan Rafferty of Stowe is among them , charged with attempted murder . The father claimed that his son had been `` manipulated '' and `` corrupted , '' insisting that his son is a `` mild-mannered gentleman . '' The other suspect in the case -- 52-year-old Richard Beasley of Akron , as identified on a Summit County court website -- is being held on unrelated charges . No attorney was listed for Beasley in the court document . The investigation began the night of November 6 , when a Noble County deputy sheriff responded to a call and came upon a `` white , middle-aged man being treated for a gunshot wound to the right arm , '' according to Hannum . The shooting victim , who is from South Carolina and was not identified by police , told the sheriff he had answered an ad on the Craigslist website offering work caring for cattle on a 688-acre property . WJW : Body of missing Massillon man identified . He met with the two suspects and drove with them toward Stock Township . After being told a road was closed due to a landslide , the South Carolina man got out of the car to start walking toward the property , which he was told was nearby . He told the sheriff that , while walking through a heavily wooded area , he then turned around `` to see a gun pointed at his head . He deflected the gun and ran '' -- getting shot in the arm while fleeing , according to the sheriff . The victim hid for seven hours in the forest before going to a house and requesting help , Hannum said . Then , on November 11 , the sheriff received a call from a Boston , Massachusetts , woman who said her twin brother had not been seen since October 22 in Parkersburg , West Virginia . The brother had also answered a Craigslist ad `` and she felt very sure it was the same advertisement ( the shooting victim from South Carolina ) had answered . '' On November 15 , authorities -- including agents from the FBI and Ohio 's Bureau of Criminal Investigation , plus `` cadaver-sniffing '' dogs -- found `` the body of a white male buried in a shallow grave '' near where the first man had been shot , Hannum said . Police have not identified the body . The sheriff tied that man 's death to the investigation of the shooting that left the South Carolina man wounded in the arm . Multiple authorities since then have also linked the two bodies discovered Friday -- including that of Kern -- with the same investigation . Zach Kern , 19 , told CNN that he last saw his father November 12 after he 'd gone with another son for the job interview . `` He was all stoked about it , '' Zach Kern said of his father 's feelings about the opportunity to work on the cattle farm . `` My brother ... thought the whole situation was sketchy . '' Timothy Kern ended up going to the would-be job site alone , not with the 17-year-old son who 'd accompanied him to the interview , Zach Kern said . The same son added that his father , divorced and with three children , worked `` odd jobs '' including recently as a street cleaner in Canton . He said that his father saw his children daily , adding that the whole family is struggling to come to grips with his death . `` We 're just trying to get through this , '' Zach Kern said Saturday .
