A teenage girl who was shot when a classmate opened fire inside their Maryland high school is brain dead and is being removed from life support, her mother said Thursday.

Melissa Willey told news reporters Thursday night that her daughter, 16-year-old Jaelynn Willey has “no life left in her.” She said Jaelynn would be removed from life support during the evening, by the family’s decision.

The mother, holding a young baby, said, “On Tuesday … our lives changed completely and totally forever. My daughter was hurt by a boy who shot her in the head and took everything from our lives.”

The teen was shot Tuesday by 17-year-old Austin Rollins at Great Mills High School in St. Mary’s County.

Rollins died after shooting Willey. A school resource officer got there within a minute and fired a shot at Rollins, but it’s not yet clear whether Rollins was killed by the officer’s bullet or took his own life.

The St. Mary’s County Sheriff’s Office said Wednesday Rollins and the girl had been in a relationship that recently ended.

“All indications suggest the shooting was not a random act of violence,” police said in a statement.

Willey had been in critical condition at the University of Maryland Prince George’s Hospital Center. A fundraising page to help her family has raised more than $59,000.

Jaelynn was one of nine siblings, her mother said, and a member of the swim team.a
