LITTLE FALLS, N.J. (CBSNewYork) — Kyle Daniw said hello as his newborn came into the world nine months ago, and on Wednesday night he was saying hello to legal charges after allegedly having a sexual affair with a 16-year-old female student.

At the Wayne home he was arrested at Wednesday morning, neither he nor his wife were talking.

Investigators said the history teacher met the student inside the halls of Passaic Valley High School when she was a freshman and that their affair occurred the following year.

“Him and the girl, everyone knew they were being very flirty with each other,” Dominique Brown, the suspect’s former student, told CBS 2’s Sean Hennessey.

Brown had Daniw for a teacher and a coach last year.

“He was good. He was a really funny guy. It was really unexpected what happened,” Brown said.

Authorities said the basketball and track coach supervised the girl in a number of sports activities.

“Overall, he was really a good coach and I just don’t know what happened,” said student Michael Giovannucci.

Giovanucci said Daniw was his track coach last year.

“I’m just shocked. That’s my initial reaction. Just really shocked,” he said.

“It’s not something you want to hear. It’s kind of disturbing actually,” added Giovannucci’s mother, Lori.

Most of Daniw’s neighbors didn’t want to talk about the charges.

“I’m just really very surprised. I mean I wouldn’t have thought he would have ever done anything like that,” Barbara Bogert said.

The 32-year-old Daniw is out on bail and out of work. He’s been suspended from his teaching and coaching jobs.
