Seeking Victim Information in Mark Altherr Investigation
The FBI’s Cincinnati Field Office is seeking to identify potential victims of Mark Altherr, who was recently charged with and arrested for possession and distribution of child pornography after investigators found a significant number of posts he allegedly made online depicting minor victims of sexual exploitation. The victims were between the ages of five and 12. It has been alleged Mark Altherr has been posting images of child pornography since 2021.
During the relevant time periods, Mark Altherr was a fitness education teacher in the Oak Hills Local School District in Cincinnati, Ohio. He may have also taught previously in the Denver, Colorado, area.
Investigators are still investigating allegations of misconduct and criminal violations that may have been committed by Mark Altherr and are seeking the public’s assistance in identifying potential victims.
If you believe you and/or your minor dependent(s) were victimized by Mark Altherr or if you have information relevant to this investigation, please fill out this short form.
If you know of someone else who has possibly been victimized by Mark Altherr, please encourage them to complete the form or contact their local FBI office for assistance.
The FBI is legally mandated to identify victims of federal crimes it investigates. Victims may be eligible for certain services, restitution, and rights under federal and/or state law. Your responses are voluntary but may be useful in the federal investigation and to identify you as a potential victim. Based on the responses provided, you may be contacted by the FBI and asked to provide additional information. All identities of victims will be kept confidential.
A criminal complaint and subsequent arrest merely contains allegations, and defendants are presumed innocent unless proven guilty in a court of law.
