Brentwood Man Sentenced To More Than Eight Years In Prison For Receipt Of Child Sexual Abuse Materials, Possession Of Unregistered Firearm

OAKLAND - Michael Lee Patterson was sentenced today to 103 months in federal prison for receipt of child pornography and possession of an unregistered short-barreled rifle. U.S. District Judge Haywood S. Gilliam, Jr. handed down the sentence.

Patterson, 44, of Brentwood, was indicted by a federal grand jury on April 18, 2024, and pleaded guilty on May 21, 2025, to both counts. According to the plea agreement, Patterson attempted to meet an individual whom he believed to be a 13-year-old girl to perform sexual acts on her. After his arrest, Patterson was found to be in possession of over 600 videos and 1,000 images containing depictions of minors engaged in sexually explicit conduct. Law enforcement also found Patterson in possession of a short-barreled rifle, which he had not registered with the National Firearms Registration and Transfer Record, as required by law.

United States Attorney Craig H. Missakian, U.S. Secret Service (USSS) San Francisco Field Office Special Agent in Charge Shawn Bradstreet, and Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) Acting Special Agent in Charge Robert Topper made the announcement.

In addition to the prison term, Judge Gilliam also sentenced Patterson to a 10-year period of supervised release and ordered him to pay restitution. The defendant was immediately remanded into custody to begin serving his sentence.

Assistant U.S. Attorney Jonah P. Ross is prosecuting the case with the assistance of Claudia Hyslop. The prosecution is the result of an investigation by the USSS, ATF, Silicon Valley Internet Crimes Against Children Task Force, the Brentwood, Concord, and Walnut Creek Police Departments, and the Contra Costa Sheriff's Office.
