Bad hair day.
From another web report
The 29-year-old woman, identified as Adrian Blanche Swain, was arrested and charged with attempted murder, San Diego police said.
Swain had been at the 619 Barber Shop on 30th Street near University Avenue earlier in the day where she had a design shaved into her hair, said customer R. Williams.
He said she seemed happy with the new ‘do. But a short time later Swain came back. It appeared that she had shaved the design off her head, he said.
