SAPULPA, Oklahoma - Creek County prosecutors filed more charges against a former Sapulpa 2nd grade teacher who police say had heroin in her purse at school.

Police arrested Megan Sloan on drug and embezzlement complaints Monday, May 1, 2017 at Holmes Park Elementary. According to court records, the assistant superintendent called police after Sloan left her Facebook account open on another teacher's computer.

Administrator Johnny Bilby told police the second teacher could see a conversation where Sloan was talking about using and selling heroin as well as pawning items that belonged to the school, an affidavit states.

Police say Sloan admitted using drugs before they searched her purse and found heroin.

Sloan now faces five charges, including drug possession in the presence of a minor, child neglect, two counts of embezzlement and possession of drug paraphernalia. The neglect charge is for the students in her class.

Sloan is being held in the Creek County Jail. She's due back in court on May 24, 2017.
