 A mansion party in Montgomery was shut down before it could even start today. The event was supposed to take place in the 5900 block of Sundown Road in Laytonsville, but Montgomery County police say after speaking with the owners of the home, they got them to agree to contact the promoters and cancel the party. The promoters have been telling ticket holders the party isn't happening, and police made sure to be on the scene at the expected arrival time to ensure that those who weren't aware became aware.
