The suspect charged in the nation’s largest school shooting since Virginia Tech changed his name a decade ago in Fairfax County because he felt his birth name sounded too much like a girl’s.

One L. Goh, a 43-year-old South Korea native charged this week with killing seven people in California, was born Su Nam Ko. But in February 2002, he filed a petition to change his name because, he wrote, he did “not like my current name because it sounds like a girl’s name,” the Associated Press reported.
