Authorities say the sister of LSU coach Les Miles has been killed in a car accident near Baton Rouge.

Danyelle Doucet with the West Baton Rouge Parish Coroner's office says Ann Browne was killed at the scene of the wreck Friday in Addis, a small town about 10 miles southwest of Baton Rouge. She says no one else was injured but wouldn't release any other details.

The Baton Rouge Advocate reports that the 54-year-old Browne was pulling out of a subdivision when her car was struck by a pickup truck.
