‘Seinfeld’ may have inspired Sniper killer

The ex-Marine charged with shooting American Sniper author Chris Kyle and another man was not legally insane, a prosecution expert said, suggesting the man may have gotten some of his ideas from the television show Seinfeld.

Prosecutors called rebuttal witnesses yesterday in the trial of Eddie Ray Routh, who is charged with killing Kyle and his friend Chad Littlefield. Routh’s attorneys, who are pursuing an insanity defence, rested their case on Thursday.
