Registered Sex Offender Arrested In Katonah For Sexual Exploitation Of Minor

KATONAH, NY — A registered sex offender was arrested Monday in Katonah and was accused of sexually exploiting a minor.

Joon H. Kim, acting U.S. Attorney for the Southern District of New York, said David Ohnmacht, 36, persuaded a 14-year-old girl to “engage in sexually explicit activity, video it and transmit it via Instagram to him.

The complaint against Ohnmacht also charged that he engaged in the conduct while being a registered sexual offender.

He was presented in White Plains federal court and detained without bail.

Kim said that Ohnmacht allegedly convinced the girl to send him sexually explicit videos of herself and threatened to release it to her friends if she did not send more.

“It is one of law enforcement’s most important missions to protect children from this type of allegedly predatory conduct,” he said.

If convicted, Ohnmacht faces a mandatory minimum sentence of 35 years in prison and a maximum sentence of 50 years in prison.

According to the complaint:

From November 2016 through February 2017, OHNMACHT communicated online via Instagram with a 14-year-old girl (“Victim-1”) and convinced Victim-1 to take and transmit sexually explicit videos of Victim-1 to OHNMACHT.

OHNMACHT utilized the screen names “Dannyw290” and “little.kitty.love” during his communications with Victim-1. OHNMACHT told Victim-1 that if she did not make and transmit additional videos, he would expose Victim-1’s prior videos to her friends on Instagram.

OHNMACHT was convicted on August 19, 2003, in Westchester County Court of multiple sexual abuse and sexual assault charges including Sexual Abuse in the Third Degree, Possessing an Obscene Sexual Performance by a Child less than 16 years old, Rape in the First Degree, Use of a Child less than 17 years of age in a sexual performance, Possessing a Sexual Performance by a child less than 16 years of age, Sexual Abuse in the First Degree, Promoting a Sexual Performance by a child less than 17 years of age, and Sodomy, Intercourse, Forcible Compulsion. OHNMACHT was sentenced to a term of imprisonment of 40 months to ten years. He served approximately nine years in prison and was released on or about November 1, 2011. OHNMACHT then began a five-year term of post-release supervision with New York State Parole that ended on or about November 1, 2016.

OHNMACHT’s prior convictions involved four different victims, who ranged in age from 13 to 15. As a result of his convictions, OHNMACHT was required to register with the New York State Sex Offender Registry.

OHNMACHT was arrested yesterday morning in Katonah, New York.
