BLOOMINGDALE, Ill. -- Police in a Chicago suburb say a Wal-Mart employee has died after setting himself on fire outside the store where he worked.

Police watch commander Randy Sater says 58-year-old Larry Graziano of Carol Stream set himself ablaze late Thursday outside the store in Bloomingdale. It was not immediately clear how he caught on fire, but Sater says lighter fluid was involved.

The Cook County Medical Examiner's office says Graziano was taken to a hospital and pronounced dead early Friday.

Sater says Graziano told police he "couldn't take it anymore."

Police say bystanders tried to help, but Graziano fought them off.
