<p>Americans were still reeling from the elementary-school massacre in Newtown, Conn., when Justin Carter allegedly committed his crime in New Braunfels, a city in central Texas.</p><p>"I think I'ma [sic] shoot up a kindergarten and watch the blood of the innocent rain down and eat the beating heart of one of them," the 19-year-old wrote Feb. 13 on a public Facebook page in response to a taunt by one of his friends. The posting came some two months after a gunman killed 20 children and six adults at the school. Reuters</p><p>Several Facebook users also reported Justin Carter's comments to the social-media company and authorities, according to Ivan Friedman, his lawyer.</p><p>Mr. Carter and his parents say the comments were made in jest. But local prosecutors are treating them as a terrorist threat, a third-degree felony that carries a punishment of two years to 10 years in prison.</p><p><a href="http://online.wsj.com/article/SB10001424127887324260204578583482948367730.html">Keep reading...</a></p><p>Read also:</p><p><a href="http://arstechnica.com/tech-policy/2013/07/teen-remains-jailed-after-violent-comments-posted-on-facebook/">Teen remains jailed after violent comments posted on Facebook</a> (Ars Technica)</p><p><a href="http://www.cbsnews.com/8301-504083_162-57592338-504083/justin-carter-texas-teen-jailed-since-feb-after-making-alleged-facebook-threat/">Justin Carter, Texas teen, jailed since Feb. after making alleged Facebook threat</a> (CBS News)</p><p><a href="http://www.npr.org/blogs/alltechconsidered/2013/07/03/198129617/teen-jailed-for-facebook-comment-reportedly-beat-up-behind-bars">Father: Teen Jailed For Facebook Comment Beaten Up Behind Bars</a> (NPR)</p><p>Explore: <a href="http://news.google.com/news/more?ncl=d0cdfm6FWKZcGHMj-Q3Lwmqqs4bLM&ned=us">186 additional articles.</a></p>
