CASPER, Wyo. (AP) — Officials say a Casper teenager accused of trying to poison her stepmother with eye drops was trying to keep the stepmother quiet after the teen told her she'd molested a young girl.

The revelation came Tuesday in a Natrona County hearing. The Associated Press reports that Alexis Jennings allegedly wanted her stepmother "gone" after the stepmother revealed Jennings' secret.

Jennings was arrested in November for reportedly poisoning her stepmother with at least 15 bottles of Visine during the course of four months. She was charged with aggravated assault. The stepmother was hospitalized twice.

Authorities say Jennings had confessed to her stepmother that she was sexually attracted to children and had molested a young girl. When the stepmother told Jennings' then-boyfriend about her stepdaughter's revelation, Jennings decided to retaliate.
