A former Denton youth pastor has been charged with child sex trafficking in connection with incidents dating back to 1997 after being arrested at his Denton home earlier this month, according to the U.S. Department of Justice.

Robert Shiflet, 50, is charged with three counts of transporting a minor across state lines to engage in illegal sexual activity and one count of coercing a minor to cross a state line to engage in sexual activity, the U.S. Attorney’s Office for the Eastern District of Arkansas announced in a news release Wednesday. Shiflet worked in Little Rock, Arkansas, and in Denton as a youth pastor.
