Not that unusual: Cops show up to bust a teen party involving booze, and find someone hiding in a bedroom. Unusual: That person is the home's 56-year-old owner, and mother to the 18-year-old who threw the bash.

Police say they arrived at the home in Naples, Fla., just after midnight yesterday, to find beer cans, bottles, and pot in the yard; as they approached, the partiers went inside and shut lights off, reports ABC7.

Mariel Weinand, 18, answered the knock on the door—with the assistance of the two girls who were keeping her upright, say police—and passed along her mom's cell phone number.

Police rang Carolyn Weinand, who said she was unaware of the party and out of town. She also gave them the OK to break up the party, which they moved inside to do.

And that's when they say they found people hiding in a number of rooms and closets—and Carolyn Weinand hiding in a bedroom. She then changed her tune: The Naples Daily News reports that Weinand kept making "statements trying to justify having the party and allowing alcohol," per police, among them that she thought they'd be safe if they didn't have to drive.

She says she didn't buy the booze, but she's charged with 26 counts of selling, giving, or serving alcoholic beverages to persons under the age of 21 all the same.

Both mother and daughter were hit with one count of having an open house party. (Weinand certainly isn't the first parent to get caught at a teen party.)
