BETHLEHEM — Marvin Sontz of Delmar was sentenced on Tuesday morning to two years in state prison, followed by 10 years of post-release supervision, before Judge Thomas A. Breslin in Albany County Supreme Court.

On June 7, according to a release from the Albany County District Attorney’s Office, Sontz had pleaded guilty to attempted promoting a sexual performance by a child as a sexually motivated felony. After being released from prison, Sontz will have to register as a sex offender.

In December 2016, an investigation was opened by the Bethlehem Police Department after it was reported that Sontz sent suspected indecent material via an online app to a 14-year-old girl he knew, the release said. The investigation uncovered that on Dec. 9, 2016, Sontz attempted to procure a photograph of a performance of a child in a sexual situation on the internet. The guilty plea fully covered and satisfied all charges stemming from that investigation.

Assistant District Attorney Jennifer McCanney of the Special Victims Unit prosecuted this case.
