ODESSA - A substitute teacher at the Ector County Independent School District has been arrested.
He's accused of texting pictures of his genitals to a teenage girl.
21-year-old John Rodger Hughes was taken into custody on Wednesday by Homeland Security Agents.
Investigators say he sent pictures of his penis to a teenage girl in Michigan.
We're told the two sent sexual text messages to each other for more than a year.
During that time, the teenage girl sent inappropriate pictures of herself to Hughes.
Agents searched Hughes' home in Odessa on Wednesday.
Hughes has been charged with transferring obscene material to a minor, possessing child porn and coercion of a minor.
Ector County ISD officials tell NewsWest 9, Hughes was hired as a substitute teacher in October of 2013 and worked off and on until February 21, 2014. We're told he substituted at several junior high and high school campuses.
Right now, Hughes is jailed behind bars in Odessa without bond.
Hughes is scheduled to appear in court on Tuesday.
