Sandy police, Gresham business played roles in conviction of Cory Kettner for incidents spanning 2016-2018

A Portland-area man who pleaded guilty to using multiple stolen credit cards to make more than $20,000 in fraudulent purchases, including at least one in Gresham that led to his arrest, will serve 40 months in prison, Multnomah County District Attorney Rod Underhill announced Tuesday.

The conviction of Cory Kettner brings a conclusion to three pending criminal cases Kettner had outstanding in Multnomah County. Kettner pleaded guilty to two counts of aggravated identity theft and one count of first-degree aggravated theft.

On Dec. 18, 2018, a person contacted the Sandy Police Department after someone, later identified as Kettner, had used a credit card in his name and made more than $11,600 in fraudulent purchases between Nov. 25 and Dec. 3. During the investigation, law enforcement recovered the victim's credit card in Gresham after an alert store employee suspected the card was being used unlawfully. The credit card had been used several times to make jewelry purchases.

On Dec. 20, 2018, Portland police responded to an art supply shop in the 5000 block of Southeast Milwaukie Avenue on reports of a fraudulent credit card use. Law enforcement learned that on multiple occasions, Kettner made online purchases using stolen credit cards in an amount less than $1,300.

When police located and arrested Kettner, they found some of the stolen credit cards he used inside a bag in his possession.

"Identity theft can happen to anyone and the amount of financial damage that can be done to a victim is enormous especially if the theft isn't caught within a very short period of time," said Multnomah County Deputy District Attorney Kate Williams, who litigated the case. "Here, Cory Kettner had unfettered access to multiple stolen credit cards and was able to use them before the accounts were flagged as suspicious."

Upon his release, Kettner will have one year of post-prison supervision.

As part of October being National Cybersecurity Awareness Montt, the Multnomah County District Attorney's Office offers the following tips:

- Only provide your personal identifying information to individuals/organizations that you trust and who need that information

- Avoid email and phone scams by deleting all suspicious emails and/or hanging up on all suspicious phone calls

- Before clicking on any link within an email, confirm the authenticity of the email. Email addresses and websites can easily be spoofed to make them appear official.

- Set up automatic bank account notifications. Some financial institutions will allow you to set daily purchase limits.

- Consider freezing your credit with all three major credit bureaus. If you need to apply for credit or a loan, you can unfreeze them at that time. This will prevent someone from opening a credit card in your name.

The Multnomah County District Attorney's Office recognizes the Sandy Police Department, the Beaverton Police Department and the Portland Police Bureau for their efforts investigating these cases.
