Montgomery County teacher charged with 14 counts of sex abuse of students A former Montgomery County music teacher has been charged with more than a dozen counts of sexually abusing young girls on school grounds, police said Tuesday morning. Lawrence Wesley Joynes, 54, of Dundalk, is charged with 14 counts of sex abuse of a minor, one count of third-degree sex offense, child abuse, and second-degree rape. (Montgomery County Police) - Lawrence Joynes. Detectives said the charges relate to the alleged abuse of 15 female victims, all in kindergarten through second grade, at New Hampshire Estates Elementary School in Silver Spring, where Joynes was a music teacher. Fourteen of the victims were students in Joynes's music class between 2005 and 2013, police said. The 15th victim was allegedly assaulted in the 1990s and is now an adult. Police said the alleged abuse took place in Joynes's music classroom on school grounds. The investigation into Joynes began in February 2013, when Homeland Security and Baltimore County police determined that Joynes was in possession of child pornography. Authorities searched his home and classroom, where they found videos and images of children on Joynes's computer and other devices. The footage showed the victims, directed or assisted by Joynes, imitating sexually suggestive gestures. Joynes was also shown inappropriately touching the girls, police said. Montgomery County detectives used the videos and photographs to identify 14 victims. Police have also identified a 15th victim, who is now an adult. Joynes allegedly had unlawful sexual encounters with her during a three-year period in the 1990s. Joynes was arrested Feb. 27 on child pornography charges. On Aug. 8, Joynes was charged with 14 counts of sex abuse of a minor and one count of third-degree sex offense relating to the recent alleged abuse. He has also been charged with second-degree rape and child abuse in connection with the case in the 1990s. Joynes, who is in custody at the Baltimore County Detention Center, has not returned to teaching since his February arrest. He was a Montgomery County Public Schools teacher for about 27 years and taught at New Hampshire Estates Elementary School for about 10 years. A Montgomery schools spokesman said in April that a school investigation would follow the criminal investigation. Joynes has taught at 11 Montgomery public schools, including Eastern Middle, Francis Scott Key Middle and Cannon Road Elementary. In some instances he split his time between schools. Anyone with information, or who was a victim and has not reported it to police, should call 240-773-5400.
