## Official Statement

Matthew Buckley, 42, of Pinole, has been charged with not just stealing two assault rifles from an Antioch resident in 2020, but also with forging documents with two judges’ signatures in an attempt to cover up the thefts. But testimony by Buckley’s old colleagues raise questions as to just how far the alleged forgery went, and whether it was limited to the bench.
