In Phylicia Barnes murder case, prosecutors say sex video includes victim, alleged killer Last year, federal authorities filed search warrant applications describing a "child pornography" investigation, while seeking access to the Facebook pages and e-mail addresses of Barnes, 16, and at least three other people, according to court documents. It is not clear how the video relates to the murder charge against Michael Maurice Johnson, the 28-year-old ex-boyfriend of Barnes's 29-year-old half sister, Deena Barnes. Prosecutors do not comment on pending cases, but they wrote in the motion that it will be played during Deena Barnes's testimony. The video was "recorded and stored" on Deena Barnes's phone and is more than 16 minutes long, prosecutors wrote in the motion. Prosecutors asked to close the courtroom because two of the people who appear in the video are minors. "The state does not wish to maintain the closure of the courtroom for questions asked to Deena Barnes subsequent to the video," prosecutors wrote. Contacted Friday, the husband of Phylicia Barnes's mother, Janice Mustafa, declined to comment. Her father, Russell Barnes, said he was not aware of the video and also declined to comment, except to say, "We're just staying focused." One of Johnson's attorneys, Ivan Bates, said the defense will challenge the prosecutors" motion to close the courtroom, adding that the "community has the right to able to see any and all evidence." Though the state will introduce the video, Bates said it also is relevant to Johnson's defense because it will "show the relationships between all of the individuals in that moment in time." Russell Neverdon, another attorney for the defense, noted that prosecutors have said Phylicia Barnes told others she felt "uncomfortable" around Johnson. "This is to the contrary," he said. The motion is the latest in the lead-up to Johnson's trial, scheduled for late January. Both sides are expected to argue the motions in a Jan. 8 hearing. Johnson is accused of asphyxiating Barnes, then moving her body after placing it in a 35-gallon plastic tub. A neighbor, prosecutors said in court this summer, saw Johnson sweating and struggling to move a tub out of Deena Barnes's Northwest Baltimore apartment. Phylicia Barnes, who was from Monroe, N.C., went missing in late December 2010 while visiting her older sisters. She planned to go to college there after graduating early from high school, where she was an honors student and ran track. Authorities said she vanished without a trace. After a widely publicized search that drew national media attention, her nude body was found floating in the Susquehanna River in April 2011.
