LAKE CITY, Fla. (AP) — Prosecutors in the case of two young North Florida sisters accused in fatal shooting of their 16-year-old brother say they’re considering dropping charges against the youngest girl and greatly reducing charges against the other.

Third Circuit State Attorney Jeff Siegmeister said Tuesday he’ll make a final decision after a Thursday court hearing.

The Jan. 5 shooting resulted in the arrests of a 15-year-old girl and her 11-year-old sister on second-degree murder charges.

Documents show the elder girl suffered years of abuse, including being locked in her bedroom for days with only a blanket and a bucket to use the bathroom. Siegmeister says those details and the girls’ ages are being considered in any charges.

The Associated Press is not naming members of the family because of the girls’ ages and because of abuse allegations.
