1982’s X‑Men: God Loves, Man Kills is a graphic novel (sort of an American tankōbon) by Chris Claremont, with illustrations by Brent Eric Anderson. God Loves, Man Kills was in its day considered something of a classic.
Two African-American children flee — but not quickly enough. Their pursuers corner and murder both of them. The pursuers leave the bodies on display and add signs explaining their motivation for the lynching: both were mutants.
