Oceanside Drug Dealer Sentenced to 10 Years

NEWS RELEASE SUMMARY – June 17, 2024

SAN DIEGO – Sean Keenan O’Connor of Oceanside was sentenced in federal court to 10 years in prison for money laundering, and firearms and drug trafficking offenses, including distribution of fentanyl, cocaine, methamphetamine, marijuana and alprazolam.

According to O’Connor’s plea agreement, deputies with the San Diego Sherriff’s Department executed court-authorized search warrants on the defendant’s residence and car on February 28, 2023. Deputies seized a semi-automatic pistol; 2,617 fentanyl tablets; 209 methamphetamine tablets; 24.19 grams of cocaine; 4,384 alprazolam tablets; and 1,549 grams of marijuana. Deputies also seized about $150,000 in U.S. currency and 0.27 in Bitcoin – which he has admitted were proceeds from drug trafficking.

According to the United States’ sentencing memorandum, the defendant demonstrated callousness and extreme disregard for human life. In one text exchange, he called people who overdose on fentanyl “dummies” and bragged on social media about the product he was selling and the amount of money he was making through drug dealing. He also posted photographs of himself on Instagram with cash and drugs.

“This significant sentence of a prolific North County drug dealer is a meaningful victory for public safety,” said U.S. Attorney Tara McGrath. “By removing dangerous criminals, weapons, and drugs from our streets, we are ensuring a safer community for all.”

“This convicted criminal will spend a decade in prison allowing him the opportunity to think of his reckless actions uncovered by special agents with HSI and our partner agencies,” said Christopher Davis, acting special agent in charge for HSI San Diego. “HSI prioritizes protecting communities against illicit drugs and activity that cause irreparable damage to those involved. HSI is determined to apply all the tools in our investigative arsenal to counter the fight against drugs.”

This case was prosecuted by Assistant U.S. Attorney Sarah Akhtar.

This prosecution was a result of the efforts of the Fentanyl Abatement Suppression Team (FAST). Formed in September 2022, the group known as FAST is a multi-agency task force led by Homeland Security Investigations working in conjunction with state and local agencies to target significant fentanyl distributors in San Diego County. FAST is an initiative under the San Diego Imperial Valley HIDTA, whose mission is to identify and disrupt fentanyl smuggling and distribution networks in San Diego County.
