Joseph Grunwald, of Brooklyn, N.Y., was sentenced to 30 years in federal prison on Oct. 22 for enticing a minor to engage in sexually explicit conduct and receiving child pornography, federal prosecutors said.
The 34-year-old had received probation twice for sexually abusing children. He pleaded guilty in August.
Grunwald solicited explicit images from two boys online in 2023 while registered as a sex offender, prosecutors said. He distributed one boy’s image in a group chat without the boy’s knowledge and later threatened him, including after chasing him through a synagogue.
“The defendant has demonstrated that he poses a grave danger to children,” stated Joseph Nocella Jr., U.S. attorney for the Eastern District of New York.
Grunwald’s prior convictions involved sexually abusing a 7-year-old girl in a synagogue and a 13-year-old boy. He received 10 years of probation in the first case and three years of probation in the second.
