Sources told WUSA the inside of the house was trashed during the party, with beer seeping through the ceiling into the basement.

Police discovered 200 partygoers just on the first floor. Another 50 to 75 people were huddled in the garage.

Underage drinkers hid in closets, under beds and anywhere they could find when officers moved in, police said.

The house was so packed, investigators estimated the air temperature to be 100 degrees.

Alcohol was so abundant, a preliminary breath test registered .09, just in the ambient air. That’s above the legal level of intoxication for a Maryland driver.
