Woman grabs gun after finding front door open. Intruder lunges at her — and she pulls the trigger.

A South Carolina woman arrived at her Greenville County home Friday morning after dropping off her children at school and discovered her front door was open, WSPA-TV reported, citing a family member of the woman.

The woman also smelled something strange, the station reported.

At that point, she went to her car and got a gun — for which she carries a concealed weapons permit — and returned to her home where she found a man in her closet, WSPA said.

And when the man lunged at her, the woman fired her gun, the station reported.

Greenville County Sheriff's deputies told WSPA the woman fired at least one round before going back outside and calling law enforcement.

Officers found the man dead in a closet, the station said.

A WSPA reporter noted that the woman's family said they believe she knew the intruder.

Deputies are investigating, the station said.
