He's in prison for sexually abusing a former student. Iowa took his teaching license.

Editor's note: This story has been updated.

Iowa revoked the license of a middle school teacher convicted of sexually abusing a former student.

Christopher Joseph Nielsen, 41, pleaded guilty in June to sexual abuse in the third degree, a felony. He is serving a 10-year sentence in the Newton Correctional Facility. Once released, he will have to register as a sex offender and be subject to lifetime supervision.

The Iowa Board of Educational Examiners permanently revoked Nielsen's teaching license after a hearing in March. The board typically waits for criminal proceedings to conclude before moving forward with licensing sanctions.

According to court records, the student's parents contacted Clinton police with concerns that Nielsen had an "uncomfortable relationship" with their daughter. The girl was 15 years old at the time.

They told police than Nielsen had attended her sporting events and bought her gifts. They also found a man's jacket and cologne in their daughter's bedroom and notes from their daughter about the time the two had spent together.

The teen told police she met Nielsen when he was a middle school teacher and she was a student.

They would talk on social media, which continued through the summer and into the following school year.

The police investigation found they met five times, either near Clinton High School or Clinton Community College. The meetups were typically arranged through social media.

She told police they met at a hospital parking lot and allegedly had sex in the back of Nielsen's Toyota Camry, according to court records. A surveillance video confirmed the location of their cars, according to a May 2016 criminal complaint.

Nielsen was arrested but released on bail and issued a no-contact order.

He was arrested a second time after contacting the student through Snapchat, a social media platform, and in person, according to court documents. The student told police she and Nielsen engaged in sexual activity while he was out of jail.

"The defendant speaks of additional sexual activity and having a child with the minor victim," the court document says.

Clinton Superintendent Gary Delacy declined to comment on the advice of the district's attorney.

On a court form Nielsen filled out in May 2016, he reported earning about $50,000 a year.

At the time, he said he lived with his retired parents, and that he has two children who did not live with him.

Clinton is located along the Mississippi River about 40 miles north of Davenport.
