Emmanuel Miller, 16, and Zachary Watson, 17 are charged as adults, police said. They and Calvin Lockner, 28, face numerous charges in the alleged beating of James Privott, including attempted murder, assault and harassing a person because of race or religion, according to court documents.
Lockner is a white supremacist with the nickname "Hitler," Baltimore police spokesman Anthony Gugliemi told CNN.
Baltimore Police Commissioner Fred Bealefeld told reporters some of Lockner's tattoos seem to indicate his affiliation with racist groups such as the Aryan Brotherhood, according to audio comments posted on the Web site of CNN affiliate WBAL.
There is no evidence the teenagers were affiliated with any white supremacist groups, Gugliemi said, but the two knew Lockner.
