A Bronx teen girl in foster care died yesterday, but her death does not seem suspicious, police sources said.

Khailaysha Bunch, 17, was found unconscious after a fight with another person in foster care about 3 p.m. in her Castle Hill home on Effingham Avenue near Lacombe Avenue, sources said.

EMS rushed her to Jacobi Hospital, but she could not be revived.

Bunch had a pre-existing medical history, which may have led to her death, sources said.

The medical examiner will determine whether there is any criminality.
