Four teenagers were arrested and charged with disorderly conduct on Tuesday after three of them allegedly had sexual intercourse on a beach in Cape Cod, Mass., while people cheered them on. The teenagers have been identified as Molly Hines, 19, of Penfield, NY, Lukas Kaminski, 19, of Hopkinton, Mass., Stephen Cerrone, 18, of Quechee, Vt. and Julianna Murphy, 18, of Penfield, NY. Kaminski was arrested for not leaving the area although officers told him to. An unidentified 17-year-old male, who was reportedly in the water with the three others, is slated to appear in juvenile court on Monday. Investigators said the teenagers may have been drinking at the time. A crowd gathered around the group chanting "USA" as police responded to the scene.
