An Upper West Side middle school teacher was caught with 1,000 photos and videos of child porn — some featuring kids as young as 3, authorities said.
Ross Lanvin, who sources say most recently taught math at MS 256 Lafayette Academy, allegedly used a fake name to create a burner Google account to keep his sick stash from September 2021 to December, Manhattan federal prosecutors said.
Lavin, 41, was arrested Feb. 13 on two counts of possession of child pornography, according to the US Attorney’s office in Manhattan.
In December, Google flagged approximately 150 images and 90 videos apparently containing explicit content to the National Center for Missing and Exploited Children, and blocked Lanvin from accessing the account, according to the Manhattan federal court filing.
The NCMEC sent the perverted files to investigators, and authorities found even more child porn while searching Lanvin’s Manhattan apartment, according to prosecutors.
Lanvin was listed in public records as living in Harlem.
Lanvin allegedly also used the burner Google account to look up lesson plans and teaching resources, once using the AI chatbot Gemini to find math problems to put on a quiz, and also to search “gay teen boys” and browse a porn site, according to court papers.
In May, the Google account was even accessed from a city Department of Education device, investigators said.
Lanvin allegedly confirmed that the Google account was his and admitted to accessing child pornography, prosecutors said in court papers.
Lanvin was listed as a sixth-grade math teacher at Lafayette Academy from at least August 2020 through last year, according to archived versions of the school’s website.
A video on the school’s Instagram account from March 2023 captioned “Mr. Lanvin” shows the teacher on stage at an event getting a plate of whipped cream smashed in his face by the principal and a student.
Lanvin was released on $75,000 bond on Feb. 18 and is due back in court in March, according to court records.
The investigation is ongoing and anyone with more information is urged to contact the SDNY.
Lanvin has been on city DOE payroll since 2006, according to online records, and still has active teaching licenses for grades 1-6 and bilingual education.
A DOE spokeswoman declined to list the schools Lanvin has worked at over the course of nearly 20 years, but said the charges were “extremely concerning” and that he has been “reassigned away from students pending the outcome of the arrest.”
“If convicted, we will pursue termination,” she added.
He faces a maximum sentence of 20 years in prison.
Lanvin’s lawyer did not respond to inquiries from The Post.
