TULSA, Okla. — The Tulsa Police Department said a man was arrested after he allegedly sent hundreds of unwanted sexually explicit pictures and videos of himself to multiple victims.

Police said officers began an indecent exposure with an electronic device investigation on Feb. 19.

The 39-year-old victim told police that around 10 years ago, Christopher Suder, her biological brother, sent her sexually explicit pictures and videos of himself. The victim told their mother and stopped all contact with Suder.

The victim said Suder started sending her sexually explicit pictures and videos of himself again after their mother died in 2021.

The victim told police while she and Suder were discussing memorial shirts for their mother’s death, he sent her photos of their mother on Facebook Messenger, asking to choose one for the shirt. Suder then told the victim to scroll up higher and there were multiple pictures of his genitals.

The victim said Suder had sent countless explicit pictures and videos over the years. Suder also used 10 to 15 fake accounts with different names to send messages.

Suder started sending messages from another fake account on Feb. 16. The victim gave investigators a screenshot of a picture of Suder’s hand and bare genitals.
