Vallejo Tax Cheat Knockum Gets 3+ Years

SACRAMENTO, Calif. – Kenneth Knockum, 48, of Vallejo, is headed to federal prison after being sentenced to three years and ten months for perpetrating a brazen tax refund scheme, U.S. Attorney Phillip A. Talbert announced today. Knockum was convicted of three counts of filing false claims against the United States, a calculated attempt to defraud the government and line his pockets.

The case, years in the making, took a dramatic turn when Knockum skipped his scheduled sentencing date on May 10, 2016. A no-bail bench warrant was issued, and he remained a fugitive until his arrest in Vallejo on March 14, 2017. This act of defiance only compounded his legal troubles and demonstrated a clear disregard for the justice system.

Evidence presented during a three-day bench trial in January 2016 revealed Knockum’s sophisticated, yet ultimately failed, attempt to exploit a loophole in the tax code. He utilized an “OID tax fraud scheme,” fabricating substantial amounts of Original Issue Discount income – a specific type of investment interest. Knockum didn’t stop there; he falsely claimed large portions of this fabricated income were withheld by financial institutions and already paid to the IRS, all to justify massive refund requests.

The sheer audacity of the scheme is staggering. One tax return demanded a refund exceeding $1.4 million, while another sought over $500,000. To support these outlandish claims, Knockum generated bogus 1099-OIDs and other critical tax forms. He then exploited a specialized IRS electronic filing system – typically reserved for financial institutions and brokerage firms – to submit these fraudulent documents. It was a complex web of deceit, designed to appear legitimate.

While the IRS flagged the majority of these false returns as frivolous, the agency still suffered losses of over $125,000 in fraudulent refunds that were actually disbursed before the scheme was uncovered. This isn’t a victimless crime; it’s a drain on public resources and a slap in the face to honest taxpayers. The investigation, conducted by the IRS Criminal Investigation division, meticulously pieced together the evidence, exposing Knockum’s elaborate fraud.

Assistant United States Attorney Roger Yang skillfully prosecuted the case, bringing Knockum to justice. This sentencing serves as a stark warning: attempting to defraud the government, no matter how complex the scheme, will be met with serious consequences. The Grimy Times will continue to follow federal crime cases in California and beyond, exposing those who seek to profit from illegal activity.
