WEST PALM BEACH, Fla. -

Authorities have released a 911 call made in the case of a Jupiter woman accused of killing her ex-partner's 2-year-old daughter.

Kimberly Lucas appeared in court Friday. The 40-year-old woman is accused of first-degree murder in the death of the girl and attempted first-degree murder of the child's 10-year-old brother, who police say was drugged.

The 911 call was placed by the boy, who can be heard crying on the tape. He tells dispatchers he "took a pill to help me sleep" and that he feels dizzy.

Prosecutors are seeking the death penalty for Lucas, who was considered a second mother to the children. She remains held without bond.

The Palm Beach Post reports she's next due in court in November.
