Former Tucson counselor accused of making child porn

TUCSON, Ariz. (13 News) - A former mental health counselor in Tucson has been accused of making and possessing child pornography.

Homeland Security said 33-year-old Xiomar Diaz was arrested on federal charges.

As of 3 p.m. Saturday, he was being held in the Pima County Adult Detention Center without bond. He is expected to also face state charges in the case, as the Tucson Police Department was involved in the investigation.

HSI said Diaz worked for a large behavioral health care organization in southern Arizona and was around multiple children. He has also been accused of talking with other kids online using the usernames “velander12″ and “XiXi.”

The federal agency is asking parents of children who may have come into contact with Diaz to call 1-866-DHS-2-ICE, use the online tip form HERE, or call local law enforcement.

DHS said Diaz was talking with a 15-year-old Tucson boy through Snapchat. The two allegedly exchanged graphic videos, and Diaz later convinced the boy to meet up for sex. Investigators said they found a video of Diaz and the teen having sex in the back of Diaz’s vehicle.

Investigators said they also found child sexual abuse material on Diaz’s electronic devices when a warrant was served in May 2026.

The investigation began in late 2025, when Diaz allegedly uploaded child porn to Dropbox. Dropbox reported the images and videos to law enforcement.
