Former SSC coach pleads not guilty

SOUTH SIOUX CITY, Neb. -- A former South Sioux City High School assistant football coach is pleading not guilty on charges that he sexually assaulted a student.

25-year-old Nathan Rogers was arrested in March. He was charged with child abuse and first-degree sexual assault of a child.

The charges stem from allegations by a 15-year-old girl at the school that he sexually  assaulted her at his home last December.

Rogers claims he admits to having relations with the teenager, but says the she "came onto him."

After being arrested in March, investigators seized Rogers's mobile phone. Court documents say they discovered numerous video clips of Rogers engaging in explicit actions with a different minor.
