Former OU Professor Charged With 131 Counts Related to Child Pornography

EDMOND, Okla. (KOKH) — A former OU Health Sciences professor has been charged with 131 counts, ranging from manufacturing child pornography to lewd acts with a child.

The charges against Allan Wiechmann go back to 2013, when he’s accused of touching a 6-year-old girl inappropriately.

According to court documents, on March 8, 2021, a DHS investigator reported sex offenses against Wiechmann to Edmond police after being contacted by Wiechmann’s wife.

Wiechmann’s wife told DHS that hidden cameras were installed in their home. She told the investigator that Wiechmann had lots of cameras around the house for “security” purposes.

When police called Mrs. Wiechmann a few days later, she told officers she found hidden camera pictures on her husband’s phone after leaning in to kiss him goodbye.

Court documents state Mrs. Wiechmann recognized the angle of the camera was coming from above a bedroom doorway. She noted fresh spackling over the location where the camera was located.

After the phone call, officers showed up at Wiechmann’s house on March 10 to investigate. In an affidavit, a detective stated Wiechmann admitted that he placed a hidden camera in a teenager’s bedroom.

“Wiechmann told me I would eventually discover his internet searches on his phone, and that I would find them odd or disturbing,” a detective wrote in the affidavit.

The detective said Wiechmann admitted he was interested in “voyeurism” and liked to watch women in dressing rooms or bedrooms.

The detective also said Wiechmann told him he used fantasies and pharmaceutical drugs to be aroused in order to have sex with his wife.

After reviewing the affidavit, Oklahoma County District Attorney David Prater charged Wiechmann with 131 counts.

• Counts 1-12 are related to having a hidden camera placed in a teenager’s bedroom.
• Counts 13-20 are related to touching a young girl from when she was 6 years old to when she was 10 years old.
• Counts 21-44 are related to using a camera to record a teenager in the nude while she was sleeping.

Other charges allege Wiechmann used Photoshop to create a photo from a video of a teenager sitting on a couch in the nude.

On Sept. 27, 2020, Wiechmann was accused of manufacturing child pornography by using a decoy smoke detector hidden camera to create a photo of the teenager standing in a room in the nude.

Wiechmann is accused of using that same decoy smoke detector hidden camera in 12 other instances over the course of four months, leading to 12 more charges related to the camera.

Three months after the 20 charges were originally filed against Wiechmann, Oklahoma City police contacted Edmond police saying they had four University of Oklahoma devices Wiechmann used that needed to be examined, including two desktop computers and two external hard drives.

Following the investigation of those devices, additional charges were filed, totaling the counts at 131.

Wiechmann’s next court appearance will be on Jan. 13.
