SAN DIEGO -- For decades the Girl's Club of San Diego has been regarded as a non-profit organization with a mission to teach young girls life skills, including cooking and etiquette. However, video obtained by the 10News I-Team paints a different picture.

"It's the Girl's Club being used as an after-hours nightclub," said one witness.

In the video, empty liquor bottles are seen in the Girl's Club kitchen.

"It was $10 to get in the building, drink all the liquor you want, come on in, no age, no rules, from 12 to 8 in the morning," one witness told 10News.

According to police reports, "Alcohol was being served after hours and minors were being admitted. Condoms and empty liquor bottles were found after the party."

"That is just absolutely ridiculous and (a) lie," Girl's Club President Clifton Blevins said. "I defy seeing a police report that says any of that."

Blevins said the party in question was thrown by a group renting the Girl's Club building and that nothing malicious happened. He added that renters help the Girl's Club keep the doors open.

The I-Team also found hundreds of donation checks made out to the Girl's Club. At the club's building, there are signs that landscaping has been neglected and trash littered around the premises.

"Do donations keep the doors open? Where does the money go? What is the money used for?" 10News' Mitch Blacher asked.

"Your money would go just like any organization that serves these types of purposes your money would go," Blevins said.

He also said money first goes to administrative costs and then to club programming.

According to the last available tax return, in 2005-2006 the Girl's Club reported more than $377,000 in revenue.

The California Department of Justice has sent several letters requesting proof the Girl's Club funds have gone toward non-profit work.

The IRS said no tax information has been filed for the Girl's Club of San Diego since 2006.
