Police say a 17-year-old girl was stabbed to death by another teenager in suburban Atlanta.

Alicia Chilton of the Cobb County Police Department said 18-year-old Olivia Smith of Canton has been charged with felony murder in the death of Abbey Hebert of Acworth. Hebert was found dead Saturday in the front yard of a home in Cobb County.

Chilton says Smith was arrested near Hebert's body.

Smith is being held at the Cobb County Adult Detention Center without bond. It's not clear whether Smith has an attorney.

The motive and relationship between Smith and Hebert was not clear.

Chilton says the incident remains under investigation.

Local news media reports that about a dozen students gathered Saturday night for a vigil in Hebert's memory at Allatoona High School.
