His parents sent him to special camps for children with behavioral problems, but by age 20, he was in prison. There, he joined a white supremacist gang and ended up in solitary confinement, a place his parents believe soon worsened his troubled mind.
He was freed in January, but two months later, he was dead in Texas.
His mother, Jody Mangue, says her son was more complicated than news media stories imply.
"He was not a follower by any means," she posted in an online memorial site.
