Sheriff's officials in southwest Florida say a clerk at a 24-hour food store shot and killed a man who tried to rob her and take her 1-year-old daughter.

Store owner Del Ackerman told the Naples Daily News (http://bit.ly/rnKaJe ) his granddaughter shot the man after he stormed into the store Tuesday afternoon and demanded money and grabbed the stroller that held her baby.

Authorities say 22-year-old Elizabeth Easterly was alone in the store with her 1- and 2-year-old daughters. Collier County Sheriff's spokesman Jamie Mosbach says the man was acting erratically before the incident.

Mosbach says the clerk shot the man as he headed toward the door with the child. He was taken to a hospital where he died of his injuries.

The sheriff's department is investigating.
