ROLLING MEADOWS, Ill. (AP) — Authorities say a 29-year-old suburban Chicago woman attempted to kill her son and daughter by lacing their apple juice with crushed tranquilizers.

Krystle El Khatib of Schiller Park appeared Thursday in Cook County court in Rolling Meadows on attempted murder charges. A judge set her bond at $1.5 million. Her public defender says she has no criminal history.

She is accused of mixing powder from crushed-up anti-anxiety pills into juice and forcing her 9-year-old son and 4-year-old daughter to drink it on Sunday. Authorities say she was angry at the children’s father and had sent him a threatening message.

Officials say the children have recovered and are in the custody of their father.
