JACKSONVILLE — A 1-year-old's mother who was fatally shot outside a Florida gas station pleaded "Please don't let me die" to an attendant who came to her aid.

The Jacksonville Sheriff's Office says 24-year-old Sahara Barkley was killed late on New Year's Day.

According to news reports, store clerk Nyla Garner said Barkley had left her vehicle running, and it was taken by a man.

Garner says Barkley confronted a woman who was with the man, and gunfire followed. Garner rushed to help Barkley.

She said Barkley kept saying, "Please don't let me die, I got a baby."

The department released surveillance video showing a woman whom detectives are trying to identify.

The Florida Times-Union reports that Barkley's family confirmed her death and thanked Garner for trying to save her life.
