OMAHA, Neb. (AP) — A former English teacher convicted of sexually assaulting a 15-year-old Omaha student has been sentenced to prison.

A judge Wednesday sentenced 37-year-old Bryan Black to 32 to 60 years in prison.

Black pleaded no contest in January to attempted sexual assault of a child and visual depiction of sexually explicit conduct.

Prosecutors say Black began a relationship with a Millard North High School student in September 2014. The girl made her allegations in March 2015, a day before Black was arrested.

Black apologized in court Wednesday. His attorney asked for the minimum sentence of three years in prison, noting that Black was previously a military police officer who suffered from post-traumatic stress disorder.
