A Jamestown man found with an illegal weapon last year will now serve time in state prison.

Carlos Rivera Leon was sentenced Monday on a conviction of third-degree criminal possession of a weapon and violating probation.

The sentence — two to four years on the weapon possession charge and two years, plus one year of post-release supervision, on the probation violation — follows Rivera Leon’s arrest in October 2022 in which he was found in possession of a semi-automatic pistol. The city man was stopped by Jamestown police on West Second and Sprague streets for a traffic violation when he was reportedly found with the weapon.

At the time, police said Rivera Leon did not possess a New York state pistol permit, and had multiple felony convictions. He was initially charged with second-degree criminal possession of a weapon.

In April 2022, Rivera Leon had been sentenced to probation on a conviction of fifth-degree criminal possession of a controlled substance.

He pleaded guilty to a reduced weapons charge in December, the Chautauqua County District Attorney’s Office announced Monday. He was sentenced by County Court Judge David Foley.

“DA (Jason) Schmidt would like to thank the Jamestown Police Department for their hard work on this case and the Chautauqua County Probation Department for their diligent supervision of probationers,” the DA’s office said in a statement.
