CINCINNATI, Ohio -- An Edgewood high school teacher resigns after admitting to taking students to a Dayton gay bar where the teenagers got their hands on alcohol.

Lori Epperson submitted a letter of resignation Thursday. She also sent an email to her supervisor and the school principal in which she admits to taking four female students to a club called Masque.

Sources tell 9News that Epperson's 18-year-old daughter was among the teens.

School officials launched an investigation after learning about the incident. They describe it as "inappropriate" conduct for a teacher.

Epperson had a contract with Butler Tech but taught marketing at Butler County's Edgewood High School. This was her first year teaching, according to school officials.

In an email obtained from Epperson's personnel file, Epperson explained that she didn't agree with the girls wanting to go to the gay establishment, but if they were to go, she thought she should go with them.

Epperson wrote, "I talked with their parents to get permission which they did give. I assured them there would not be any drinking. I also made it very clear to the girls there would not be any drinking. They agreed."

According to the club's Web site, you have to be 18 years old to enter. One of the girls was 17, according to school officials. Epperson goes on to write that the girls asked to go to a different part of the bar and when she went to look for them they had run into someone they knew.

She writes, that person gave the girls shots and cosmopolitans. When she learned what happened she immediately took the teenagers home.

"I apologize for not telling you the truth from the beginning," wrote Epperson. "I accept the consequences and believe I should not be in the environment where I make a negative impression on kids. I made a very bad decision that I have regretted ever since." she wrote.

School officials say they don't think there's any legal action they can take against Epperson. They are working with legal counsel to determine if they can go after the bar where the teens were allegedly served alcohol.

The board is expected to accept Epperson's resignation at the next meeting.

When a 9News crew went to her house for comment, the person working in the yard said Epperson did not want to talk.
