Former Local Music Teacher and Filipino Man Charged With Sexually Exploiting and Sex Trafficking Children

BOSTON – A former local school music teacher and a Filipino national living in Baltimore, Md., have been charged with allegedly sexually exploiting and sex trafficking minor children.

Joshua DeWitte, 50, of Cambridge, Mass., was indicted by a federal grand jury on Oct. 29, 2025 on six counts of sexual exploitation of children (and attempt and conspiracy); one count of conspiracy to commit sex trafficking of children; one count of distribution of child pornography; and one count of possession of child pornography. Christopher Allan Tisoy, 27, a Filipino national residing in Baltimore, Md., was charged by an Information on Oct. 29, 2025 with one count of sexual exploitation of children (and attempt and conspiracy) and one count of conspiracy to commit sex trafficking of children.

The defendants were arrested in May 2025 and charged with one count each of sexual exploitation of minors (and attempt and conspiracy). They remain detained in federal custody.

According to the charging documents, at the time of the alleged conduct, DeWitte was a music teacher at a local school in Massachusetts. Tisoy, a citizen of the Philippines who lawfully entered the United States in September 2024 on a H-1B Visa, was employed as a medical technologist at the Sinai Hospital of Baltimore.

In December 2024, DeWitte was allegedly identified as the owner of a Snapchat account that uploaded child sexual abuse material (CSAM) depicting the abuse of a boy who appears to be between approximately eight and 10 years old. Snapchat records allegedly showed that, in September 2024, DeWitte requested nude pictures from multiple purported minors; sent pictures of his penis to the purported minors; and discussed previous and potential in-person meetups for sexual relations with minors. Additionally, it is further alleged that DeWitte paid, and offered to pay, another Snapchat user to obtain and produce child pornography and to recruit minor boys for himself.

Based on that information, DeWitte was arrested and charged in Cambridge District Court with six counts of disseminating obscene material to a child, one count of distribution of material depicting a child in a sexual act and one count of possession of child pornography. He was later released on conditions.

According to the charging documents, a Telegram conversation between DeWitte and Tisoy was located on DeWitte’s phone, in which they arranged for the production of videos depicting the sexual exploitation of minor boys in the Philippines. Specifically, it is alleged that in the conversations, DeWitte and Tisoy negotiated the terms of creating sexually explicit videos involving minors, including which minors should be involved; which sex acts the minors should perform; who should film, including whether a third party or one of the minors themselves should film; what angles should be filmed; and how much DeWitte should pay Tisoy for each video. The negotiation allegedly incorporated the sexual preferences of both DeWitte and Tisoy, with both agreeing on what they would each find sexually gratifying. Tisoy then allegedly relayed instructions to the minor victims to create a video.

DeWitte allegedly paid Tisoy for each video Tisoy produced and sent. It is further alleged that, between July 3, 2023 and Dec. 27, 2024, DeWitte sent 87 PayPal payments to Tisoy, in amounts ranging from $27 to $958, to film the sexual exploitation of minors in the Philippines – totaling to approximately $23,752.
