A 14-year-old Mississippi girl allegedly murdered her mother — who was a teacher at her school — and shot her stepfather, police said.

Ashley Smylie, 40, a high school algebra teacher, was found shot to death in her Brandon home, east of Jackson, Tuesday afternoon by her husband, according to WLBT-TV.

The man was then confronted by Smylie’s 14-year-old daughter,  Carly Madison Gregg, who was brandishing a pistol, news station WJLT reported.

He wrestled the weapon away from her, but not before she shot him in the shoulder, according to the report.

The alleged teen killer then jumped over a backyard fence and fled the area. She was tracked down by authorities near the home and arrested for murder and attempted murder.

She appeared Wednesday in court, where she pleaded not guilty to the charges. Her bond was set at $1 million.

The young suspect reportedly attended Northwest Rankin High School in Flowood, where her slain mom had taught.

““Our deepest prayers and condolences are with our Northwest Rankin family during this difficult time. We love our Cougar family. You are not alone,” the city of Flowood said in a statement.

Rankin County Sheriff’s Office could not immediately be reached for comment Thursday morning.
