Missouri Man Sentenced to Federal Prison for Second Internet Stalking Conviction

SAN ANTONIO – A Missouri man was sentenced in a federal court in San Antonio on Wednesday to 72 months in prison for internet stalking.

According to court documents and evidence presented at trial, from May 2020 to September 2020, Mark Joseph Uhlenbrock, 69, with the intent to harass and intimidate another person, used the internet to engage in a course of conduct that caused substantial emotional distress to his victim.  This course of conduct included posting nude photographs of the victim on the internet without the victim’s consent. Uhlenbrock was convicted by a federal jury at trial in May.

The conduct from this crime occurred while Uhlenbrock was still on supervised release for a 2016 federal conviction for internet stalking the same victim.  In 2016, Uhlenbrock was sentenced to 41 months in federal prison, followed by three years of supervised release, after Uhlenbrock pleaded guilty to the same offense against the same victim.  As part of his plea in that case, Uhlenbrock admitted that from January 2006 to August 2015, he caused substantial emotional distress by posting nude photographs of his victim on the internet without the victim’s consent.

“For years, Uhlenbrock weaponized the internet to try and destroy one woman's life—not just once but twice,” said U.S. Attorney Jaime Esparza for the Western District of Texas.  “My hope is that this sentencing provides a sense of relief for the victim and sends a message that online stalkers like Uhlenbrock will be brought to justice.”

“This is a horrible crime with real consequences and trauma to the victim. Our agents and law enforcement partners are working to prevent these types of crimes every single day,” said Special Agent in Charge Oliver E. Rich Jr. for the FBI San Antonio Division.  “No one should have to live in fear of their private lives being posted online for revenge by someone they trusted.”

The FBI investigated the case.

Assistant U.S. Attorneys William Calve and Karina O’Daniel prosecuted the case.
