SCARSDALE, NY -- A bust of prostitution-based money laundering in the New York tri-state area—which resulted in 20 indictments being handed down—has ties to Scarsdale, Attorney General A.G. Schneiderman announced Tuesday.

David Mendelowitz, a former guidance counselor and Dean of Students at Scarsdale High School, paid for prostitutes and bought crack-cocaine, according to a criminal complaint. "During the time span of his alleged criminal conduct, Mendelowitz was involved in many student programs, including Scarsdale High School's Drug and Alcohol Task Force," police said.

The Scarsdale10583 site wrote at the end of the 2011-2012 school year of a "surprising turn of events" in which Mendelowitz unexpectedly announced his retirement. "Mendelowitz has been out for several weeks due to illness and as a result of the sudden timing of his decision no remarks were prepared for the meeting," the report said.

This same Scarsdale1583 post listed his biography, which reportedly included achieving a PhD degree in Counseling from St. Johns University and previously working as a school counselor in Sleepy Hollow and Horace Greeley. "He had a wonderful rapport with students and their parents and got involved with many school activities including Signifer, Senior Options, the Drug and Alcohol Task Force and many more," the website said. The racket was toppled after 16 months of investigations led by the Organized Crime Task Force and New York Police Department, and resulted in the rescue of two human trafficking victims, officials said.

Using surveillance techniques and combing through tax documents, authorities learned Manhattan-based advertising company Somad Enterprises, Inc. was creating ads online and in print to promote prostitution for its clients, police said.

Somad and its associates would mask millions of dollars in prostitution charges as antique sales, cleaning services and other falsified purchases, police added. A spate of prostitutes, bookers, managers and drivers were in on the operation, according to a press release from Schneiderman.

"This investigation led to the arrests of multiple individuals who were part of a criminal enterprise that made millions of dollars by profiting off the exploitation of women," Schneiderman said. A total of 19 people—hailing from New York to North Carolina to the Philippines—and one corporation, Somad, face indictments.
