CUSTER COUNTY, Oklahoma - A teacher at Clinton Public Schools was arrested for allegedly having a sexual relationship with one of her students.

And, according to the report, she even transported the student to and from the teacher walkout, with a group of several students, and had sex with the teen before going to and after leaving the Capitol.

Authorities say 35-year-old Keri Hoffman taught 7th grade and 8th grade Math for Clinton Public Schools when she began having the inappropriate relationship with one of her 15-year-old male students.

Police learned of the crime when Hoffman and her husband came to the police department on Saturday, where she confessed to the crime at her husband’s urging.  Hoffman told police she and the teen first began communicating on Facebook and had sex multiple times, beginning on March 30.

According to court documents, Hoffman admitted to investigators that she took a group of students, including the 15-year-old boy, to the Capitol to participate in the walkout.

On April 8, investigators interviewed the teen, who they say corroborated what Hoffman has told them about the relationship.

Authorities arrested Hoffman on Sunday and booked her into the Custer County Jail on two complaints of second-degree rape, one of facilitating sexual conduct with a minor by electronic technology and one complaint of engaging in a pattern of criminal offense. Her bond was set at $120,000.

Hoffman has been teaching at Clinton Public Schools since August 2011.

On Tuesday, Hoffman sent the following message to her students, regarding this situation:

Dear Students,

I am sorry to say I will not be returning to school as your teacher. I will likely never be a teacher again. I have lost my way somehow and have found myself in some legal trouble. I do not understand how I got here but I have turned myself to face my consequences because it is the right thing to do. I set out as a teacher with a true desire to help people and somewhere along that road I forgot what that meant. I know I have left you at a place of dismay and with no closure and I apologize for that. I hate that I have left you down and am leaving you but know that I am doing this for YOU. I have always been real and honest with you and now is no different. I have made some choices that I have to live up to the consequences of and I’m prepared to do that.

I hope that you are able to understand that “all have sinned and fallen short of the glory of God.” And for me, I have fallen far this time. I failed to spend time in prayer and reading my Bible as I should have. I knew I had these weaknesses but never gave them to God to deal with. I instead tried to handle them on my own and this is where I am. I tell you this because don’t want you taking my Christianity that I professed and believing it was a lie. My God could have helped me if I would have let him. My failures is not because I am a Christian. My failure is because I am human and I did not let God do what a Christian woman should do; be the master of my life.
