Prosecutors in the case against the accused killer of Phylicia Barnes will show a video at trial depicting the teenage victim “intoxicated and engaging in sexual relations” with her accused killer and others, the Baltimore Sun reports.

Barnes, a 16-year-old from North Carolina, went missing from Baltimore, near Pikesville, three days after Christmas 2010, while she was in Baltimore visiting her half-sister. Barnes’s body was found in the Susquehanna River in April 2011.

The search for Barnes spread out across Maryland, reaching Howard County in the spring of 2011. 

During a Maryland State Police-led search of the Patapsco Valley State Park on April 9, police did not find Barnes, but they did find a body, later identified as John H. Hagegeorge, 55, of Catonsville.

Hagegeorge died from natural causes and exposure, according to police.

Less than two weeks later, workers on the Conowingo Dam reported to police that they thought they saw a body in the Susquehanna River. The Natural Resources Police were able to recover the body, later identified as Barnes. The State Medical Examiner’s office ruled her death a homicide.

Barnes’s half-sister’s boyfriend, Michael Maurice Johnson, 28, faces first-degree murder charges in Barnes’s death. His trial is scheduled to begin in late January.

Prosecutors say Johnson suffocated Barnes, and then moved her body in a 35-gallon plastic tub, the Sun reported.
