An 18-year-old college freshman has died after she was struck in the head by a stray bullet while walking on a track in Nashville, authorities said.

Jillian Ludwig was hospitalized in “extremely critical condition” after being shot Tuesday afternoon, and died overnight, Nashville police announced Thursday morning.

Shaquille Taylor, 29, was initially arrested and charged with aggravated assault and evidence tampering for allegedly shooting, police said. In the wake of Ludwig’s death, police said they are “in discussion with the District Attorney’s Office concerning modified charges.”
