Charles County Sheriff Troy D. Berry announced today that Raymond Daniel Posey, III, 22, of Nanjemoy, was indicted for murder in connection with the disappearance of Crystal Keyona Anderson, 29, who was reported missing in Prince George’s County in August 2011 and whose remains were found near Purse State Park in January 2012. The facts of the case are as follows:

On August 2, 2011, Angela Anderson reported her daughter, Crystal Keyona Anderson, missing to the Prince George’s County Police Department. The initial missing person’s report was assigned to a detective and during his investigation he determined Crystal was last seen at a party in Nanjemoy, Charles County, MD. Detectives with the Charles County Sheriff’s Office were contacted and a joint investigation began. Investigators canvassed many areas and interviewed numerous people, however Crystal remained missing.

On January 2, 2012, a hiker was walking through a remote wooded area of Riverside Road, close to Purse State Park, when he noticed a boot with what appeared to be a bone inside; he immediately called police.

The following week detectives and evidence technicians established a large perimeter and slowly and methodically excavated a creek bed that spanned over 1800 feet and included areas three feet deep in mud and silt. With the assistance of search and rescue dogs from SARDOM ( Search and Rescue Dogs of Maryland), which are dogs specifically trained in detecting human remains, the wooded area and creek were searched. Their work resulted in the recovery of more remains and the discovery of clothing consistent with what Crystal was last seen wearing.

The remains were then examined by the Office of the Chief Medical Examiner for Maryland with the assistance of a forensic anthropologist. In February of 2012, detectives were notified the remains were indeed those of Crystal Anderson. Known medical records of Crystal were used to make the identification. Once her identity was confirmed, detectives from both Prince Georges County and Charles County notified Crystal’s mother.

After three-and-a- half years of a continuous and detailed investigation, detectives linked Posey to Crystal’s disappearance. Details of the investigation were presented to a Charles County Grand Jury and on February 13, 2015 an indictment charging Posey with first-degree murder was issued. Detectives believe robbery was the motive.

Raymond Posey is currently in the Maryland Department of Corrections serving a sentence for an unrelated armed robbery conviction.

“This was a tough case to investigate but our detectives and forensics staff never gave up. They worked closely with many resources and kept Crystal’s mother, Angela Anderson, informed almost every step of the way. Although we can’t bring Crystal back, we hope Mrs. Anderson is comforted in knowing that we care,” said Sheriff Berry.

The investigation in this case is ongoing and other people may be charged. Anyone with additional information is asked to call Det. John Elliott at (301) 609-6515.
