A 50-year-old Chesapeake man who was already a convicted sex offender has been sentenced to 10 years and one month in prison after federal authorities found child sexual abuse material on devices he was not supposed to have. William Oyster was still under federal supervision from a 2012 conviction when the new evidence surfaced during a routine compliance check.
Oyster was previously convicted in the Eastern District of Virginia of receiving child sexual abuse material on July 6, 2012, according to wavy.com. He was released from prison in November 2020 and placed on supervised release, a status that came with strict conditions meant to prevent exactly the kind of offense he's now being punished for again.
Supervised Release Conditions Violated
As part of his supervised release, Oyster's home and electronic devices were subject to search at any time, and he was barred from using or accessing online devices without prior approval from a probation officer, per the same account. Those conditions became central to the case against him when a routine search turned up equipment he had no business holding onto.
During a residence search on Nov. 12, 2025, Oyster was found in possession of two smartphones, an external hard drive and two thumb drives, the station's report states. A review of those devices revealed that Oyster possessed child sexual abuse material, triggering the new federal case that ultimately led to sentencing on Wednesday, Jan. 7, 2026, as 13News Now reported.
Arrested With a Loaded Handgun
The case took another turn weeks later. When the U.S. Marshals Service arrested Oyster on Jan. 6, 2026, he was found in possession of a loaded handgun, according to the same wavy.com account. As a previously convicted felon, Oyster could not legally possess firearms or ammunition under federal law.
That detail added a second layer of illegality to a case already built around a violation of the terms that were supposed to keep him monitored and offline. The sentencing brings Oyster's combined time behind bars, across two separate federal cases tied to child sexual abuse material, to well over a decade.
