A former second grade teacher accused of bringing syringes and heroin to school in her purse is believed to have reached a plea agreement with prosecutors and is expected to plead guilty in the case. 

In early May, a teacher at Holmes Park Elementary School in Sapulpa told school administrators that second grade teacher Megan Sloan, 27, had left her Facebook account logged in on the witness's computer. The teacher said that Sloan left open a conversation in which she discussed using heroin and pawning school property.

Administrators called police and interviewed Sloan, who reportedly admitted to bringing syringes to school, to pawning school-owned iPads for cash, and using student field trip money to pay for gas and drugs. She reportedly consented to a search of her purse, which police say contained as many as 40 syringes, some containing liquid. Investigators say that the substances in her purse tested positive for methamphetamine and black tar heroin. They say she also had the prescription medication Suboxone in her purse, a controlled substance used as either a painkiller or an alternative used to treat addiction to narcotic painkillers.

Sloan was arrested and charged with multiple misdemeanors and felonies related to the drugs and theft of school property. Charges include one count of possession of a controlled substance in the presence of a minor, one count of possession of drug paraphernalia, one count of child neglect, and two counts of embezzlement.

On Friday, Sloan appeared in Creek County District Court and waived her right to a preliminary hearing. Assistant District Attorney Mike Loeffler said that the defendant is expected to enter a guilty plea pursuant to a plea arrangement reached with the Creek County District Attorney's Office. He did not provide details about the nature of the agreement.
