A body encased in concrete and buried in a Georgia backyard has been identified as that of a former Florida journalist who went missing in August . The positive identification of 30-year-old Sean Dugas was made using dental records and facial bone CT scans , the Georgia Bureau of Investigation said Friday . Dugas , a former crime reporter at the Pensacola News Journal , had been missing since August 27 . William and Christopher Cormier , twin 31-year-old brothers , are charged with murder in Dugas ' death , according to police in Winder , Georgia , where the body was found . The brothers had earlier been charged with concealing a death in the case . Winder police went to the home of the brothers ' father on Monday , acting on information from Pensacola police , Winder Police Chief Dennis Dorsey said . The father said his sons arrived from Florida three weeks ago , and the brothers told their father they had been caring for the missing man 's dog but ended up killing the dog , Winder police said . The dog was buried in the backyard of a home that the father is renting , Dorsey said . In the yard , police unearthed a body in a plastic storage container that had been encased with concrete , Dorsey said . Authorities believe the body was buried about three weeks ago , and the concrete may have been purchased at a Home Depot , Dorsey said . When the two brothers arrived at their father 's home during the police investigation , they were detained , Dorsey said . The father has n't been charged and is cooperating with investigators , Dorsey said . Managing Editor Ginny Graybiel of the Pensacola News Journal said Dugas worked at the newspaper from 2005 to 2010 . `` He started as a clerk and became a police reporter -- along the way he did a good bit of entertainment coverage , '' Graybiel said . `` Sean was a very gentle , good-hearted soul . To be the victim of a crime like this is , of course , something we never could have imagined . '' Dugas ' girlfriend noticed he was missing August 27 when she went to pick him up at home for lunch that day , Pensacola Police Capt . David Alexander said in a statement . When she returned to the home on September 7 , she found it empty except for a television , Alexander said . A man who also lived at the house was gone , police said . The girlfriend reported to police on September 13 that Dugas was missing , Alexander said .
Authorities use dental records to identify remains of Sean Dugas . The body was found in a shallow grave on the property where he lived with his parents and siblings. Twin brothers have been charged with murder in his death .
