Who is Sharnell from Lost Boys: Why Our Sons Turn Violent and How We Can Save Them and what is their importance?

Sharnell is one of the lost boys. Garabino describes him as a tough kid, battle scarred from his life on the street. When Garabino meets Sharnell, he has already spent four years in juvelile detention facilities.... he is sixteen-years-old.

At twelve, Sharnell was dealing drugs. When he "punished" a customer who tried to cheat him by hitting him on the head with a lead pipe, the man didn't die.... a week later he stabbed Sharnell in the chest with a knife. Sharnell claims to be without fear, something negated by his rocking and thumb sucking during the interview with Garabino.
