"SBC Fire has declared an MCI (multi casualty incident) associated with multiple medical emergencies including multiple severe traumas," Santa Barbara County Fire Department Public Information Officer tweeted Saturday evening. "These are associated with heavy crowds in Isla Vista for the unsanctioned beach party known as Deltopia. Many balconies are over crowded."

In a typical scene along Del Playa Blvd on a Friday or Saturday night in Isla Vista, party goers stand on balconies and spill out into the street.
