A Virginia couple has been arrested after a party they allegedly organised for their teenage son spiralled out of control, drawing between 100 and 300 youngsters to their multi-million-dollar home, with police reporting underage drinking, disorderly conduct and fireworks.According to the New York Post, Aubrey Vaughan, 55, and his wife Lisa Vaughan, 45, were charged with contributing to the delinquency of a minor and maintaining a common nuisance following the November 6 gathering at their home in McLean, one of the wealthiest neighbourhoods in the United States.Fairfax County Police officers responded to the property on the 1400 block of Woodacre Drive shortly after 9 pm following complaints from neighbours about the large gathering.Officers found dozens of allegedly intoxicated teenagers wandering the streets, while fireworks were being set off outside the house. Police also reported the smell of alcohol and disorderly behaviour at the scene.The New York Post reported that bodycam footage showed officers questioning the couple outside their home about the gathering. Lisa Vaughan insisted that they had been supervising the party and had taken steps to prevent underage drinking.“No, we haven’t had any alcohol,” she told an officer.When an officer questioned her response, pointing out the smell of liquor and the presence of drunk teenagers, Vaughan maintained that they had been checking for alcohol and backpacks.The situation escalated further when a large firework exploded behind the house, prompting officers to rush towards the area. They were met by a crowd of teenagers shouting and running out from behind the property.Police found around 100 more youngsters in the backyard, with some climbing down scaffolding on the porch and others crowded onto the stairs. Officers eventually ordered the teenagers to leave as additional police personnel arrived.Speaking to Fox 5 DC after his arrest, Aubrey Vaughan defended the decision to host the gathering, saying the couple had wanted their son to celebrate at home under their supervision.“We want our kids at our house so we can watch them and the reality is this could happen to anybody,” he said.Vaughan claimed they had not expected older teenagers to attend an event organised for an eighth-grader.“We had zero idea that ninth, tenth, eleventh and twelfth graders would come to an eighth grader’s party. But they did,” he said.The couple later turned themselves in at the Fairfax County Adult Detention Center and were released on $1,000 unsecured bonds each.The property, estimated to be worth around $3.2 million, is an 11,000-square-foot estate with seven bedrooms and nine bathrooms, according to public records cited by the New York Post.Vaughan apologised to those affected by the gathering, saying they had not wanted the situation to unfold this way. He also maintained that there had been no alcohol at the party and that anyone found with it had been asked to leave.Fairfax County Police said the incident highlighted the importance of parental supervision when hosting gatherings involving minors. The department urged homeowners to monitor activities on their properties, take steps to prevent underage drinking and contact police if a gathering begins to get out of control.
